How heavy are tractor tires

How Much Do Tractor Tires Weigh? (2022 Updated)

Tractors are humongous machines normally used for agriculture, industrial and construction tasks. Though they weigh at least 20,000 pounds in total, they can still roll smoothly on rough terrains thanks to their tires being rated for such heavy duty chores. So the next question might be, how much do these tires weigh to support the hefty load of tractors?

Tractor tires have a variety of weights and sizes depending on purpose. These range from 300-pound small size tractor tires to a whopping 1000-pound extra large tires. When those figures are added up for all four tires, your tractor tires may weigh 1,200 to 2,400 pounds.

According to the manufacturer’s tire selection, tractor tire size and weight should be matched with the tractor’s powertrain and gross weight, for maximum torque and efficient fuel consumption. That is why identifying the weight of your tractor’s tire is important in order to improve your tractor’s traction and efficiency.

What Is The Average Tractor Tire Weight Per Size?

Tractor tire weighs will vary based on size category. Small size tractor tires can weigh up to 300 pounds. Mid-sized tractor tires are 400 pounds or more, while large tractor tires weigh between 500-800 pounds. The heaviest type, also called extra-large, weighs up to 1,000 pounds.

Small Size Tractor Tires

The smallest tractor tires are 17.5 by 25 feet in size. These tires can weigh up to 300 pounds each. For comparison, a typical car tire only weighs 25 pounds, while a pickup tire will still be outweighed by a small size tractor tire by 100 pounds.

Medium or Mid-Sized Tractor Tires

The next size is called medium or mid-sized tractor tires. These tractor tires are approximately 20.5 by 25 feet in size. There isn’t much of a size difference between these and small-sized tractor tires. As a result, the weight of each medium-sized tractor tire is not significantly different from that of the small-sized tractor tire, despite the fact that each medium-sized tractor tire weighs 400 pounds or more.

Large Tractor Tires

Tractor tires measuring 23.5 by 25 feet are considered large tractor tires. They can weigh between 500 and 800 pounds each. However, some large tractor tires are lighter, weighing between 450 and 650 pounds. The weight of a tractor tire of this size is determined by its wear patterns and the amount of metal contained within.

Extra Large Tractor Tires

Lastly, the heaviest tire size is called ‘extra large’ with weights up to 1,000 pounds. Their combined weight adds approximately up to 4,000 pounds to the total weight of the tractor.

How Do You Measure the Weight of Your Tractor Tires?

Tractor tires are quite heavy and weighing them individually on a scale can be tiresome and impractical since you will need a crane to lift and place them securely.

Instead, you can determine their weight by identifying the dimensions of each tire indicated on the tire’s sidewall. When inspecting the tire’s sidewall, you will notice a 5-digit number. The first two digits are separated by a period, and the third and fourth numbers are separated by a dash. 16.9-30 is an example of these five digits.

These digits are not random. In this example, the 16.9 refers to the width of your tractor tire from one sidewall to the other. This is measured in inches. The 30 refers to the diameter of your tire’s rim, which is also measured in inches. 

It appears to be fairly simple to determine the size and dimensions of your tires. However, this isn’t always the case because some measurements are in radial, metric, or standard units.

Radial Tractor Tires

Radial tractor tires are another thing to think about when it comes to tractor tires. The letter R, which denotes radial construction, can be found on radial tractor tires. Radial construction refers to any tire with cord piles that are 90 degrees. The cord heaps are moving in the same direction as your tires. You’ll also notice that the vast majority of tires are radial.

Radial tractor tires are identified by two digits followed by a point. Following the point, there is another number and a “R,” followed by two numbers. For example, values like 11.2R20 can be found on the sidewalls of radial tractor tires. A figure like this implies that the tire is a radial tractor tire.

Metric Tractor Tires

Also called European tires due to the measurement system they use, the digital figures on the sidewall are marked by a “R” and a slash. For example, 280/85R24 and 280/85R20.

Start with the first number, as that is the width of the tractor tire when properly inflated and mounted. If that number appears small, it is because it is expressed in millimeters rather than inches.

However, the aspect ratio relates to the second set of numbers. The aspect ratio illustrates the width of the tire in relation to its height after it has been inflated.

The letter R indicates the tire is made of radial material, which is typical in metric tractor tires. The number following the R denotes the wheel diameter for mounting.

Standard Tractor Tires

The first example above is a common tractor measurement. Those five-digit values are rather conventional and typical, yet you may come across five-digit dimensions such as 11.2X20. Don’t be perplexed by these seemingly disparate figures; they are all the same and represent the same thing. These values are simply another way of printing the measurements.

Tractor Tires Care Tips

Tractor tire care maintenance is different from regular passenger car tires mainly due to the nature of workload. That said, tractor tires need regular cleaning to prevent dirt buildup. Also, avoid driving on the pavement with them as much as possible. And since these tires are still subject for periodic replacement, don’t wait for them to severely wear out before replacing. Lastly, buy higher-quality tractor tires with a solid reputation in the industry.

Clean Your Tractor Tires

Dirt accumulates on and beneath your tractor during normal operations, particularly around the tires. If your tires are particularly filthy, Clean them after you use them at the end of the day.

Make use of water, soap, and a good tire brush. Get into the tire grooves and clean all the way to the bottom. Then, allow the tires to dry naturally. Clean tires perform better, which may allow you to enjoy them for a longer period of time.

Avoid driving on the pavement as much as possible

Tractor tires are not the same as car or truck tires. They are more suited for navigating softer ground such as mud, grass, or hay. You should try to limit your driving on the pavement as much as possible. Even though tractor tires can handle pavement, doing so is highly discouraged.

Don’t Wait to Get Replacement Tires

The longer you wait to replace those old, worn-out tires, the higher the risk. Your tire can pop at any time if you hit a sharp stone or other debris. The elasticity of the tire is sucked up by dry air and sun exposure, causing the material to crack.

Buy Quality Tires

It’s far better to spend considerable money upfront on higher-quality tires that will last you for years. You could spend several hundred dollars per tire, but cutting corners will cost you more money in the long run.

The weight of tractor tires can range from 200 pounds on the smallest up to 1,000 pounds each. Knowing the weight of your tractor’s tire can help you improve the traction and efficiency of your tractor wheels. You can determine the exact weight of each tire with careful calculations based on the dimensions provided at the sidewall.

What Are the Standard Measurements of Tractor Tires?

Luckily, you don’t have to perform the heavy lifting to find how heavy your tractor tires are. However, you need to know that they come in two major groups:

  • lightweight tractor tires
  • heavyweight tractor tires

Now, it’s crucial to remember that these groups have four major subgroups, including:

  • compact size tractor tires
  • medium/mid-sized tractor tires
  • large tractor tires
  • extra large tractor tires

1. Compact size tractor tires

What’s so unique about these tractor tires?

Firstly, they measure 17.5x25ft. Their maximum weight is estimated at 300 pounds.

However, you can consider them lighter, as the average weight of a car tire measures 25 pounds.

And, even when you compare various heavy-duty vehicles, similar to tractors, you can notice that their tires weigh around 200 pounds each.

So, there’s no mistake that the average tractor has a tractor tire weighing around 300 pounds (or even more!)


Medium/mid-sized tractor tractor tires

Medium tractor tires are the next category, measuring 20x25ft.

However, their maximum weight measures 400 pounds or slightly more.

As you see, medium tractor tires are not bigger than small tires; thus, they don’t add weight to your tractor size and weight.

3. Large tractor tires

A large tractor tire is more substantial than the previous two categories.

They’re massive due to their 23.5×25 feet proportions. Thus, the tire weight might vary between 400 and 8000 pounds at maximum.

Yet, some more substantial tire weights can also be slightly lighter. Thus, they can vary between 550 and 650 pounds.

So, the tire weight matching this size is determined by metal parts and wear patterns.

Finally, the last category in the colossal tire weight measures 26.5×25 feet. Don’t be surprised when you realize they weigh 1,000 pounds each!

Thus, the heavy tires weigh around 4,000 pounds on your tractor!

It’s insane, you’ll agree!

Determining the Weight of Your Tractor Tires

Naturally, you want to determine how much your tractor tires weigh, but how do you calculate the weight correctly?

As previously said, you don’t have to calculate by yourself, let alone detach them one by one, and measure.

The average tractor tire is too sizable for the process. So, you can stick to the following procedure:

Firstly, fire the sidewalls of your tractor tire. You should find a 5-digit number on it.

Now, once you do, you’ll see that the first two digits are separated by a period. Moreover, the last two digits should have a dash between them.

An example would be 16.9-30.

Hence, the 16.9 refers to the tractor tire’s width from one tire’s sidewall to another. The width is measured in inches.

Number 30 represents the diameter of the tire’s rim, also measured in inches.

Now, it would be ideal to stop here. Nevertheless, there are further explanations necessary for your tractor tire.

Namely, they can be:

  • standard sizes
  • radial tractor tires
  • metric tractor tires.

1. Metric tractor tires

A metric tractor tire refers to the European tire, based on its measurement system and tire weight.

You can recognize the metric measures because the tire will have a letter R and a slash or maybe two. Such examples refer to 420/85R24 or 280/85R20.

The first number means the tractor tire’s width when it’s correctly mounted and inflated to understand the digits better.

However, if the integer is small, it’s represented in millimeters instead of inches.

The next digit refers to the aspect ratio.

The aspect ratio includes the tire width percentage to its height when correctly mounted and inflated.

So, once again, The number will be smaller, expressed in millimeters, not in inches.

And the letter R refers to the radial construction. The radial construction is standard in metric tractor tires.

Finally, the number after the radial construction – R represents the wheel diameter for mounting.


Radial tractor tires

A radial tractor tire also has radial construction posted on the sidewall.

The R means the radial tractor tires have 90-degree cord piles, moving in the same direction as the tractor tires.

Also, most tires will be radial, but not always.

In addition, the radial tractor tire contains two numbers separated by a period, followed by another number, R, and again two numbers following.

So, for instance, you can find 18.4R26 or 11.2R20.

3. Standard tractor tires

To understand these tires better, refer to the first example we have used in this section. It’s standard for this tire type.

But, if you find different expressions for tire sizes, such as 16.9X28 or 11.2X20, don’t be too perplexed – these are just alternatives for the same terms on the sidewall.

However, it’s possible to convert from one tractor size to another.

You can easily refer to the Ken Jones Tires conversion chart to do so correctly.

Still, every blank spot means that there’s no correct conversion to particular tire sizes.

13.6X2413. 6R24340/85R24
14. 9X3014.9R30380/85R30
20. 8X3420.8R34520/85R34
20. 8X4220.8R42520/85R42

Therefore, you should refer to the conversion chart above to find the right size of your tires, but if you still are uncertain how to measure the correct size correctly, you can ask tractor experts.

Tips & Tricks on Keeping Your Tractor Tire Optimal

As we know, tires are an essential part of tractors, and we cannot imagine any farm equipment without them.

So, once you determine the size of your four tires, you want them to last for a couple of years, without additional complicated conversions too soon.

Thus, it would be best to keep your four tires in different shapes and top condition for more robust uses and a longer lifespan.

And how to do so? Well, you can

1. Clean the tractor tire often

If you have a farm tractor, you will undoubtedly use it on a daily basis.

Thus, the tractor will gather dirt underneath and on the construction. However, the tires will be the first to get dirty.

So, when you notice your tires are too dirty, wash them. How?

Apply a tire brush, soap, and water. Next, get in the tire’s groove and clean all the way to the tire’s bottom part. Next off, let your tire completely air dry.

Clean tires will be better for a ride, and you can easily extend their quality and lifespan.

2. Purchase quality tires

When picking the best tractor tire, you may likely spend several hundred for each tractor tire, but it doesn’t mean the tractor tire will be as good as it should be.

So, to avoid the tire falling apart or damaging too soon, you should invest in a premium-quality tire that will last for an extended period without harming quickly.

Although it might be difficult for your budget, it is still the best solution to purchase a high-quality tire to avoid all sorts of tire issues and potential risks.

3. Don’t drive on a pavement

Your tractor might handle a little pavement, but not too much – do not forget that.

So, keep in mind that tractor and truck tires are not the same!

Thus, you should limit your pavement driving to a minimum or eliminate it.

The tire weight is mainly intended for transporting different materials and operating on softened terrains, including hay, grass, or dirt.

Another reason is that in some states, such as Pennsylvania, the law forbids you to drive tractors on streets unless you title your vehicle first.

4. Replace the tires often

If you notice your tire is too old and in bad condition, an instant replacement is the best solution for your tractor.

You will reduce the potential risks whenever you drive your tractor.

Also, your tractor tire can pop whenever you hit debris and pointy stones.

So, due to proper tire size, width, and tire weight, you will definitely feel it when driving the tractor.

So, if your wheels slip more than usual, it’s time to replace the old tires with the new ones.

Unless the weather conditions are too wet, the wheels and tires should not slip like that.

If you fill-up the tire and notice it cannot maintain the pressure, it’s time for a replacement.

Also, your tires may dry rot. So, if your tractors are overexposed to the sun, it may cause material cracks and lose elasticity.

Hence, do not expose your tractors and tires to the sun and dry air.

However, you might also find the tire brittleness, paleness, or tire fading. Therefore, these are the main signs you must replace your tires instantly.

5. Improve storing conditions

To keep your tractor tires in excellent condition, you need to store them in specific airtight places.

Thus, you can prevent the evaporation of the lubricating oil within the tractor tire.

You can use various premium airtight plastic bags from different supply shops near you, including lawn or garden bags.

And when placing the tire inside the bags, ensure you release as much air as possible, and secure the bags with tapes.

6. Place the tires upright

The replacement tires for tractors should not be stacked or lying down.

Instead, it would be best if you placed them properly upright.

And, in case you need to stack them, don’t stack the tires too high. They might be damaged by falling.

However, when storing the tires, ensure they’re in a dry and cold place, avoiding direct sunlight.

A black tire might absorb the rays and heat up to 120F degrees. At this high temperature, it can tear inside or break down quickly.

How heavy should the tire be for flipping?

A tractor tire should be at least 20 inches thick to allow the athlete to perform well in the optimal flip-tire position.

Otherwise, a thinner tire will only enable a sumo-deadlift lifting position, famous as the biceps-tearing position.

How much does a semi-truck tire weigh?

A typical semi tire weight measures around 110 pounds.

The main reason for this weight is that semi-trucks better handle the more challenging road conditions, and their durability reflects in the heavier semi-tire weight.

What kind of tires do tractors use?

Tractors use the following tire types:

  • Agricultural Tractor Tires (R1)
  • Turf Tractor Tires (R3)
  • Industrial Tractor Tires (R4)

The R1 type is ideal for fieldwork primarily.

The R3 type is the best solution for lawn mowers and gold cars.

Finally, the R4 tires are the most convenient on different construction sites, specifically forklifts.

How do I know if my tractor tire is biased or radial?

A radial tractor tire has a two-part construction, allowing the tire sidewall to flex independently of the thread area or face of the tire.

On the other hand, the bias tractor tire is created with a single-ply wrapped diagonally from one side to another.

How much does an 18 wheeler tire weigh?

The tire weight may vary due to the wheel materials and their weight.

Thus, the wheel – the metal part may weigh around 30-50 pounds for a standard trailer or a tractor-sized vehicle.

However, when you add a tire, the situation changes.

Thus, the weight might reach 100 pounds if the tire is new.

But, according to the tire’s diameter, height, and size, the weight will also vary.

And we have seen that the weight goes from around 100 pounds for semi-trucks to 1,000 pounds for extra-large tractors.


So, how much does a tractor tire weigh?

They may weigh around 300 to 1,000 pounds based on the tire size.

Their weight must also match your tractor’s weight and size, so it would be best to learn the tractor’s size and weight as well and fit them correctly.

However, you have already seen how to correctly measure the tire weight with the given number on the sidewall.

Still, when you know these digits, they will be valuable for adding extra weight if you need to improve your tractor’s traction and perform better in various lawn tasks, as well as on a regular basis.

Thus, make sure you find the weight specifications in the size chart given above and follow the proportions for the correct sizes.

And, if you have additional questions, dilemmas, or other difficulties, comment below – I’ll gladly help you solve them.

Tractor tire size and pressure MTZ 82

Tractor tires are selected based on operating conditions. Tractors of the Minsk Tractor Plant (MTZ) are universal and are used very widely: when clearing snow on the streets, plowing fields and harvesting, etc. Accordingly, there is no universal “rubber” option for them. It all depends on how the equipment will be used: on what soil, in what speed mode, etc. The model also plays a role - it is obvious that a heavy tractor needs larger and stronger tires than a compact “mini”, and the pressure in tires MTZ 82 will be different than in the chambers of a forest tractor type L82.2. Sets for the front and rear axles are selected separately. nine0003

The MTZ 82 tractor tire consists of a chamber and a tire. The chamber serves to hold air in the inner cavity of the tire. The chamber walls and tires filled with compressed air perceive the loads acting on the tire. The tire consists of a tread, carcass, breaker, beads and sidewalls.

The carcass acts as the main strength of the tire, whose characteristics determine its load capacity and strength. The frame is made of several layers of special rubberized cord fabric, whose layers are tightly superimposed on each other. The tread is a running part of the tire made of a three-dimensional rubber layer, tightly fitting the carcass. The lugs and tread depressions form a pattern, the shape of which determines the grip of the tire with the ground surface. The breaker is a cushion layer made of soft rubber and serves to soften the impacts transmitted from the tread to the carcass. The sidewalls of the tire have much thinner covering layers of rubber and serve to protect the sidewalls of the carcass from damage. On the rim, the tire is fixed with the help of the beads. Inside the boards are wire rings wrapped with the ends of the carcass cord layers. Wire rings increase the rigidity of the tire beads and prevent them from stretching. nine0003

Pneumatic tire MTZ 82:

  1. tread;
  2. breaker;
  3. frame;
  4. sidewall;
  5. bead rings;
  6. board.

The chamber is filled with compressed air through a valve with a spool installed on it, which is a reverse-acting valve. The design of the tire valve for the rear wheels of the MTZ 82 tractor allows you to connect to it a device for filling tires with water or a similar liquid for ballasting the tractor. nine0003

Sizes and their selection

Usually MTZ 82 rear tires are 15. 5R38, front tires are 11.2-20. For each MTZ model, the manufacturer has established the recommended sizes of "rubber". Dimensions are selected according to the inner size of the tire, it must match the outer diameter of the rim. Otherwise, the owner has the right to choose between low- and high-profile tires, based on working conditions and financial capabilities.

Rear tires size 15.5-38 are distinguished by a reinforced breaker and radial placement of cords in the carcass. Tires, whose carcass has a diagonal arrangement of the carcass cord thread, form a tire profile plane with an angle of 50-54º, and tires with a radial design - their angle does not exceed 5º. The radial arrangement of the cords gives the tire better flexibility. Also, these tires improve the traction and grip qualities of the tractor, compact the soil and slip less, and have a longer tread wear life. nine0003

Operation and maintenance of MTZ tractor tires 82

The technical condition of the tires affects the traction and coupling qualities of the tractor, its fuel consumption, throughput and productivity. Thus, we can safely say that tires largely determine the productive and economical operation of the tractor. In addition, tires are expensive and wear parts of the tractor, the cost of which is about 12% of the cost of the tractor itself. Tires are changed 3-4 times during the entire life of the tractor, therefore, the cost of operating tires is approximately 20% of the total cost of operating the tractor. nine0003

The service life of a tire is affected not only by compliance with the rules of operation, but also by the conditions in which they are used: air humidity and temperature, road surface and soil properties. When using the tractor in the field, the service life of the tires is about 6000 hours, and when performing transport work, they wear out much faster. On stony soils, in mountainous areas, the tire life is reduced by 25-35%, and on winter snow cover, on the contrary, it increases by 25-30%. nine0003

The front drive tires MTZ 82 wear out faster than the rear ones. This is due to the fact that the rolling radius of the front tires is 1. 7 times less than that of the rear ones. Passing the same path, the front tires make more revolutions.

To prevent rapid tire wear, it is recommended to adhere to the following rules:
  • Strictly observe the norms of internal tire pressure, depending on the working conditions and loads on the tractor;
  • When driving at high speeds, check that the tractor is not pulling to one side. If it drives, stop the tractor and inflate the tire with less pressure; nine0014
  • try to avoid sudden braking, bringing the wheels to a skid, as well as prolonged wheel slipping;
  • do not park the tractor on soil contaminated with oil products;
  • timely check and adjust the front wheel camber;
  • disengage the front axle on dry roads;
  • Avoid wobble and wobble.

Tire pressure of MTZ tractor 82

Recommendations for inner tire pressure, kgf/cm2

Type of work rear wheels front wheels
General types of work
1. 4+0.1

1. 1
For working on soft soils and plowing 1.0+0.1 1.4+0.1
For working with heavy agricultural equipment 1.6+0, 1 2.5+0.1

Violation of the norms of internal pressure in tires significantly reduces their service life. An internal pressure that is 20% lower than the norm reduces the service life by 15%, and an increased pressure reduces the service life by 10%. When performing certain types of work, temporary tire overload is permissible.

Due to the fact that there are many varieties of MTZ-80 for different tasks, the tire, respectively, can be different and differ in structure. The frame plays an important role, because all the effort and load falls on it. The correct carcass should evenly distribute the load, which increases the life of its tire and performance. nine0003

Fortunately, correct tire pressure and maintenance on your tractor will make changing a tire a breeze. According to statistics, for the entire life of the tractor, it is enough to replace the rubber 4 times. The agricultural tractor has a small feature related to the size of the wheels. For example, the diameter of the wheels is smaller in front, the rear wheels are an order of magnitude smaller. The pressure in the tractor tires on different wheels may differ, but in extreme cases, you can adhere to the indicator 1.4 kgf / cm2

How to choose the right radius of the front wheels for MTZ-82

I must say that the radiality of the front wheels R20, installed on this model of the Belarusian tractor, is optimal for standard operation.

However, the machine can also be used in winter, in conditions of high snow cover, as well as when working in quarries, swamps and in other more difficult conditions.

That is why the manufacturer allows independent intervention of drivers and the choice of wheels of other recommended parameters.

  • If the equipment makes long journeys on asphalt roads, the driver can install wheels 7 ... 8 - 18 on it, which will reduce the tread height and the tractor will become more stable on a hard surface. nine0014
  • On the contrary, when it comes to using machinery in winter, which requires a higher ground clearance, it is allowed to install wheels in dimensions 9 ... 11.5 - 22 ... 24, and the tractor will rise slightly above the ground, and soft mud hooks will begin to pave the way more confidently in deep snow.
  • When using equipment in the most extreme conditions, when driving through peat bogs or other unsteady surfaces, it will be necessary to create a large torque not only on the rear wheels, but also on the front wheels, which will require the installation of tires 12…14 – 25…26. nine0014

When installing wheels of an off-design radius, the driver should be prepared for more frequent maintenance work to repair the suspension, bearings in the hub, change the oil and other procedures, since an off-design load on all systems provokes rapid wear of all parts. 82

Mechanical wheel lock on the MTZ tractor

In some cases, on the most inaccessible sections of the road, the classic rear or all-wheel drive of the tractor cannot cope with a thick layer of dirt and return back to its track. nine0003

However, this does not mean at all that the equipment will not be able to overcome such a section, since the driver just needs to change the mode - turn on the center differential lock and brake, which will make the wheels rotate simultaneously and the tractor driver will be able to pull the car out of almost any mud.

This locking system has the following fairly simple design and principle of operation:

  • The lock itself is made in the form of two cams, each of which is securely fixed on the drives of the standard gears of the device, on the inside of the shafts, which in turn have a special grinding of the end to to ensure the play of these cams and the couplings installed on them. nine0014
  • These couplings are connected to the drive, made in the form of a separate pedal and lever on one side and, respectively, with a locking and turning device on the central shaft - on the opposite end.
  • So, if necessary, the operator simply presses the pedal of the lock drive, the clutch moves in the space allotted for it, entails the shaft and the locking device, which securely snaps onto the gear, preventing further freedom of rotation of each wheel axle separately. nine0014
  • This in-cab pedal lever is spring-loaded and automatically reversed and, if released, it will return to its original position and the differential lock will be released and the wheels will start to spin normally.
  • For a longer fixation of the lock lever for the MTZ-1221 tractor, there is a special stopper on the pedal, pressing which causes the clutch to remain in the locked position for a longer time.

Tractor tire rupture Although the mechanical wheel lock is simple in execution and reliable in operation, it is difficult to operate and non-functional. Therefore, on modern models of Belarusian technology, a more advanced system is installed - a hydraulic locking drive, which is different in that it no longer requires effort and a long arm to actuate the mechanism, since the traction force increases many times under the action of compressed oil in the piston. However, such a system can cause leakage in the piston when overloaded and more time-consuming and costly repairs to the equipment. nine0003

Why do the MTZ-82 front wheels “run”

Often, on various Internet forums, owners and operators of MTZ-82 tractors complain about the problem when, while driving on a hard surface, their wheels become loose and start to “run”, which causes discomfort in cabin, and also causes damage to mechanisms.

The reason for these problems lies in several possible breakdowns of various systems at once, and the most common of them are listed below:

  • a considerable, slightest imbalance can cause vibrations. nine0014
  • It is also necessary to determine the pressure itself, because the deep mud lugs hit the surface with force when driving at high speed, causing the tractor to sway. This effect is especially pronounced when too much pressure is injected into the wheels on the MTZ, and the driver should slightly lower the tires to a maximum pressure of 1. 2 ... 1.4 atm.
  • Traction arms may become unbalanced or loose during intensive field work. So, if such a problem occurs, it is necessary to eliminate the freedom of movement of individual parts in these elements, and the vibration will abruptly disappear. In addition to the rods, you should also check the shafts, couplings, ball bearings, bipods and sectors, each of which has a thread with nuts and, accordingly, needs periodic tightening. nine0014
  • If the tractor has passed more than a year without maintenance or survived the winter at rest, the flexible cuffs can be significantly damaged, which will inevitably lead to smudges on the hydraulic elements. This disadvantage is especially pronounced in the distribution head of the power steering, which must be eliminated by replacing the cuff or clutch.
  • One of the main problems with the appearance of the effect of loosening of the wheels is the wear of the hubs, bearings and trunnions, which leads to free lateral movement of the wheel, affects the toe and camber of the wheels, and this causes vibration, rubber erosion and other unpleasant consequences. If such a problem is discovered after disassembling the hub, it must be immediately eliminated by replacing the bearing or the assembly, as it can subsequently ruin the entire suspension on the tractor. nine0014
  • In addition, if the wear of these parts is not noticed, it is worth checking the nuts and studs for fastening the rim, since this effect is often obtained due to the banal loosening of the nuts or from the fact that an increased load on the studs breaks part of the thread from it. And also, for prevention, inspect all other washers, nuts, bushings and other fasteners or consumables.
  • Tire fitting for the MTZ 82 tractor Any problem with the smoothness of the movement of agricultural equipment requires a thorough check, since later it can easily result in more serious breakdowns. In addition, the operator or owner of the tractor should choose the nearest service center for himself and carry out periodic maintenance of the undercarriage of his unit at least once a year if there are no problems, and also regularly check and, if necessary, adjust the pressure in the MTZ 82 tires. Only with such equipment will serve for decades and does not require large investments. nine0003

    The front wheels on the MTZ-82 tractor must be replaced exclusively in pairs, since the purchase of only one tire may result in a loss of effective operation.

    That is, one side will cling to the dirt more effectively, while the old tire will begin to slip.

    All this will lead to incorrect operation of the traction rail, motor and unbalance of the entire mechanism.

Products: How much does a tractor tire weigh? | The answer will surprise you! nine0001

You've probably heard the statement, "The heavier the tire, the better the tire." Of course, mass and quality are connected, but everything is much more complicated. Today, BKT experts will explain this relationship and note the factors that affect tire mass.

Tire weight basics

The weight of a tractor tire, like any other off-road tire, depends on more than just tire size. With the same size, a tire designed for increased load capacity will be heavier, since it uses additional reinforcing elements. nine0093 BKT tyres, for example, feature a large amount of material in the bead. On the one hand, this slightly increases the mass, and on the other hand, it reduces the amount of damage to zero. In other words, with the added weight, you don't have to worry about fixing cracked tractor or loader tires.
A significant proportion of a tire's mass is in the tread. In this case, other elements, such as belts, shoulder areas, sides and carcass, should be taken into account. They are the ones that can be tested and improved during development to achieve the desired combination of performance and price. nine0003

How much does a tire weigh on average?

Still want to know how much a tire weighs? It is likely that you often look at the weight table for off-road and agricultural tires. We'll satisfy your curiosity and tell you how much some of our best-selling models weigh, from light to heavy:

  • LG 306 (1.17 kg): one of the most compact BKT tires in 11 × 4.00-5 is designed to be mounted on mowers and small tractors. Due to the special tread pattern, it does not damage the soil (including when maneuvering). nine0014
  • LIFTMAX LM 81 (9.25 kg): The smallest industrial tire in 150/75 R 8 designed for forklift trucks and terminal tractors. It features a reliable tread, excellent resistance to wear and damage, and a long service life.
  • AGRIMAX RT 600 (643.52 kg): The largest BKT agricultural tire in IF 1250/50 R 32 is the ideal choice for demanding lawns, fields and soils. The secret of its effectiveness lies in the lower tread pattern, numerous lugs and the rounded shape of the shoulder zones. nine0014
  • EARTHMAX SR 468 (3819.80 kg): The heaviest BKT 40.00 R 57 off-road tire for mining trucks. It is distinguished by an all-steel steel cord and, as a result, increased resistance to damage.

So similar but very different

AGRIMAX FORCE and AGRIMAX V-FLECTO tires in the same size 710/70 R 42 are BKT's most popular agricultural tires. The first model designed for tractors with engines over 250 hp. with., equipped with IF technology, and the second tire is designed for tractors of new generations and endowed with VF technology. nine0093 At the same time, the difference in the mass of these tires is insignificant: the first weighs 347.4 kg, and the second - 340.84 kg.

Weight is the most important element

Choosing the right tire comes down to durability, speed index, self-cleaning and puncture resistance. It is these parameters that BKT engineers are working on, creating tires for various applications. But there is another important, even fundamental, factor for any tire - its weight.
BKT invests heavily in research and technology to reduce tire weight. nine0093 Why do we strive to produce lightweight tires? Of course, tires are designed for specific applications, which determines their weight.
