How does a tire plug work

How Long Does A Tire Plug Last? Is It Safe To Plug In A Tire?

Tire plugging is the fastest method to repair a punctured car. Tire plugging uses a cord to prevent the airhead from escaping. If you are an experienced person, you can avoid damage to your car with simple tips.

So, how long does a tire plug last? Most manufacturers say that plug versions can last 7-10 years if installed correctly. 

Yet, this number is meant as a reference because you can’t always fix it perfectly. The article gathers useful knowledge and some of the most frequently asked questions about tire plugs. Let’s scroll down to read more information!

What Is A Tire Plug?

It is the primary tool in the repair by plugging method. From the outside, it looks like a standard wire, and the structure is quite remarkable; it is a sticky object; depending on the case, the item can expand or contract to match the size of the hole.

Its working principle is also quite simple: after being inserted into the tire, the plug wire will sense the pressure, determine the shape of the wound, and then automatically expand to adapt.

In addition, the material that makes the wire must be guaranteed to meet the standards, confirming the certainty so that after the air is pumped in, there will be no problems.

There is no denying the convenience that the plug method brings, and you can even repair it without removing the tire from the rim. You can even plug in the tire in some exceptional cases, even when the wheels are connected.

How Long Does A Tire Plug Last?

When a vehicle is repaired correctly and maintained, a plug’s life span can last up to 7-10 years. It is an unbelievable number for a wheel that has been repairable.

However, manufacturers advise users not to overdo patching like this in practice. When using too many repair measures, the impact will affect the inherent functions, causing deflation and explosion.  

When traveling on the road, the car’s wheels have problems, do not rush to decide when the experience is not proficient; the best way is to take the car to a repair center to have expert advice on the appropriate repair method.

Is Plugging A Tire A Good Idea?

Plugging or patching is only a temporary measure before you have enough time to change into a new tire. The life of a tire after plugging can last from 7-10 years or 25,000 miles; no one can be sure that there will not be any problems. 

Plugging in tires will be a good idea, even effective if the wheel is in an emergency that needs to be moved.

Is It Safe To Plug In A Tire?

You can safely use your plugged-in tires when traveling in a specific section of the road. Unlike a spare tire, which has a short life, it is possible to prevent air from escaping through a previous puncture completely with a plug repair method.

Via many surveys, experts think there is a better measure than a plug – radial patch. It is a suitable method available on almost all popular tires on the market.

The process takes about 30 minutes while using a wire to insert the air hole takes up a few minutes. Both must be vulcanized to reinforce and increase the rubber surface’s certainty.

Is It Ok To Drive On A Plugged Tire?

As long as the wound has adequately been reinforced, you are entirely safe traveling by car with tires. The safest time to use is not too long from when you repair using the above method.

 Besides, some notes have also ensured stability when operating this type. 

However, do not drive when there is a wound near the wall or on the side of the wheel; if the plug diameter exceeds ¼ inch, it is best to replace the tires. 

Finally, the body’s weight, do not use plug tires to carry heavy objects; this inadvertently puts pressure on the wheels when the tires are weak.

How To Plug In A Tire?

Here are some ways to help you better understand the plugging process.

Step 1: Locate the leak
  • Fill the tires with air, press to see if the pressure has reached the standard when you feel the hardness, then ok.
  • Dilute the soap and water solution and spray it all over the surface of the wheel, where there are air bubbles; that’s where the puncture is.

This step does not require you to remove the wheel altogether, but you can use a jack to support the wheel’s weight, so it is pretty easy to do the following steps.

  • Use pliers to pick up the sharp object, locating the hole.

Step 2: Drill holes
  • Use a T-tool to close the hole, of course, before doing this step, and you need to sand around the wound.
  • Pierce the damage to an appropriate extent, once the spot is round.
  • If the pin is too small to be reamed, use a hand drill with a smaller tip to expand and then machine the whole face.

Step 3: Plugs ready
  • Prepare a strip of plugs from the kit; insert the repaired string into the eyelet (plug tool). 
  • Use pliers to pull the thread through the hook to a certain length.
  • Apply a layer of cement powder to cover the thermos strip and the hole in the car’s body.

Step 4: Insert strip
  • Press the plug firmly into the hole.
  • After the pin has entered the muscle a certain length, leave about an inch outside the wheel surface, slowly remove the plug. 
  • End slot in eyelet, allowing free fall as long as the pin goes into the tire.

Step 5: Pump tires
  • Fill the tires with air again, and the required pressure index is 10% lower than the standard.
  • Spray a layer of solution all over the face to check the level of leakage occurs again or not.

Step 6: Cut off the excess
  • Use a piece of paper to wipe off the cement coating; let it cool down to dry completely (about 5 minutes).
  • Use a cutter to cut the cord, leaving only about ⅛ inch.

Step 7: Test
  • Continue to spray a layer of solution on the surface; check for the last time to see if the gas is still fizzed.
  • Remove the auxiliary equipment, to let the car return to its original state.


The above article has provided you with knowledge related to plugging or manipulations to perform this process. Hopefully, it will help you when you encounter a similar situation.

Tire Patches vs. Tire Plugs: Which Is Better?

Home » Tire Patches vs. Tire Plugs: Which Is Better?

What are tire patches and tire plugs? Well, they are useful when you get a flat tire. In such cases, there’s a good chance that a minor repair can get you back up and running again quickly.

Three of the most common of these “minor repairs” are:

  • tire plugs
  • tire patches
  • plug/patch combos

The first option, a tire plug, is cheap and fast to administer. Plugs work best when you’ve run over a nail or similar blunt object that punctures the tire and causes it to leak air. After the nail or sharp object is removed, the plug can be inserted into the hole to fix the leak. While plugs of the old days were problematic and served more as a band-aid type of repair than anything else, many plugs available today actually vulcanize to the tire to provide better stability.

Tire patch

A patch, on the other hand, is considered to be a better quality tire repair. However, it’s a bit more laborious of a repair than a plug. Patching a tire actually consists of removing the tire from the rim and then using a die grinder to clean up a 2-inch diameter around the puncture to give the patch enough of an area to bond with. The patch is then pushed from inside the tire through the outside of the tire, sealed, and let dry.

The best modern tire repair solution is a plug/patch combo product. This is one piece and it combines the best benefits of both options.

Keep in mind that not all tire damage can be repaired. For example, tire bubbles are a dangerous problem that will result in needing new tires.

DIY or Mechanic?

The question is: Can or should you repair a tire on your own?

If you purchased your tires from a mechanic or tire-specific business, then chances are they will either plug or patch your tire for free if it develops a leak and a patch or plug can resolve the issue.

Tire plug

Many tire-specific businesses will also fix your tire via these means as a way of developing goodwill with you, the customer, so that when it comes to buying new tires you’ll consider purchasing that next set from them.

However, outside of these two scenarios, tire patching and plugging aren’t necessarily expensive (usually only $10-$20 a repair), but more of an inconvenience.

Considering this, patching your tires on your own might not be worth it.

Tire Plugs and Tire Patches – DIY

DIY patching or plugging is still an option, yet we’d advise you to be absolutely sure of what you’re doing before going the patching route.

The plugging route is fairly simple (and cheap, as plug kits can be purchased for just a few dollars), as all you really need to do is locate the hole and insert the plug. Going the patching route is also fairly inexpensive, but there’s a lot more involved.

For instance, patching a tire consists of:

  • Removing the tire.
  • Removing the tire’s valve stem core.
  • Separating the tire from the rim.
  • Cleaning out the puncture hole (usually with an air die grinder).
  • Equipping the grinder with a grinding stone to prepare an area around the puncture.
  • Removing dirt/debris around the puncture.
  • Administering vulcanized cement to the inner part of the tire.
  • Administering the tire patch, working your way from the inside out.
  • Sealing the patch.
  • Put the tire back together and back on your car.

Frequently Asked Questions (FAQs)

What limitations are there with each?

Plugs won’t usually work when a puncture is near the sidewall, as it likely won’t be able to completely seal the area. Plugs are also ineffective when the puncture is on an angle. Patches are usually the better-recommended option, but they do have their limitations. For instance, if a puncture is greater than a quarter-inch in diameter, a patch will likely be ineffective and the tire may be too damaged to repair.

What’s better – tire plugs or tire patches?

Plugs, when installed correctly and in the right situations, can help a tire last for up to 25,000 additional miles. But while plugs can be effective, usually patches are considered to be the better, more secure option of the two. The patch/plug combo is the safest and most reliable option.

Are plugs just band-aid repairs?

Yes and no. Years ago they were and if they aren’t installed correctly or in the right situations today, they still are. However, today’s plugs vulcanize to the tire and can help it last for tens of thousands of miles more.

Electric chain saw problems | Causes of failure

An electric chain saw is much easier to use than a gas chain saw. Despite this, it still remains a technically complex device that needs maintenance and care. If we advise you to contact service centers to deal with difficult damages, you can learn how to fix minor faults yourself. In the article, we repair an electric saw, understand the principle of its operation and study the most common causes of breakdowns.

Design and operation of the electric chain saw

Before you check the power saw for breakdowns and repair it, you should figure out how this tool generally works.

The power source is electricity from a standard 220-volt outlet. The engine is located under the saw body, and excess heat is removed from it through special holes. The saw group, which is a tire and chain, is similar to that found in gasoline and cordless saws. The lubricant necessary for the smooth running of the chain along the guides is supplied automatically from the reservoir. An element such as an oil pump is responsible for this.

An electric motor drives a sprocket that sits next to the bar and is connected to the chain. The saw chain runs on the tire, rotating from the work of the sprocket. Sawing is carried out due to the teeth located along the chain.

Main faults of power saws

Let us briefly analyze what causes most often lead to problems with the operation of the chain saw:

  1. If the saw does not start, make sure the house has electricity. There is also a possibility that it is required to check the wiring of the saw and the extension cord through which it is connected.
  2. A popular reason why the brushes on the saw burn is their abrasion. Dust accumulates and sparks. Repair is not required, but the brushes need to be replaced.
  3. If the chain on the saw does not lubricate, make sure there is lube in the reservoir. You may have a broken pump or a clogged lubrication mechanism.
  4. If the power saw does not cut well, it may be due to power surges in the network. In this case, the saw does not need to be repaired, but your conditions may not be suitable for its operation.
  5. If the chain on the saw does not rotate, it may be that the sprocket on the saw set is clogged with wood debris. Cleaning is recommended as a repair.
  6. If the saw turns off during operation, the brushes need to be replaced.
  7. It happens that the chain saw slips under minimal load. If the electric saw does not pull, you need to disassemble the gearbox and perform its diagnostics. Perhaps it's a gear or a torsion spring.
  8. The vibration of an electric saw is an integral part of working with this tool. It is caused by the lack of a high-quality anti-vibration system.

Power saw disassembly to repair breakdowns

As an example, we disassemble the Makita UC3530A electric saw, however, in the design of different models, as a rule, there is no dramatic difference.

  1. Remove the tire with a target. To do this, unscrew the screws holding the saw group cover. Loosen the chain tension and remove the nut holding the bar.
  2. Remove brushes. Unscrew the plug, then pull out the brushes themselves.

  3. Next, you need to gain access to the rotor. Unscrew 4 screws from the body and remove the additional handle.

  4. Disconnect the mechanical and electronic parts of the saw.

  5. Remove the rotor from the housing.

  6. Disassemble the main handle. It contains the start button, internal components, as well as the soft start module and filter.

  7. This is what the coil looks like. In the same part of the housing is the current collector.

  8. Take off the star. Loosen the screws on the case you removed it from.

  9. Remove the extra handle. It will detach from the part of the body on which the oil tank is located. Disconnect if necessary.
  10. Remove the gear shaft.

  11. Remove the bearing and oil pump ring from the shaft.
  12. Remove the snap ring.
  13. Remove the gear from the shaft.

Diagnosis and repair algorithm

We examined the problems that owners of electric chain saws face, and also analyzed in detail the principle of operation and the scheme for disassembling these tools. Now let's move on to how to fix the electric saw and determine the cause of the malfunction.

Electric saw does not turn on

Imagine a situation in which the chain saw is connected to the power supply, and you hold down the start button, but nothing happens. In extremely rare cases, the saw smokes in the places of the power circuit. This may be due to a malfunction of both the tool itself and the power supply. Let's take a look at the factors to consider:

  1. Make sure that there is electricity at home: if the engine malfunction is not caused by a simple lack of power. Also, the problem may be in a specific outlet. To eliminate this factor, connect a working electrical appliance to the same place.
  2. Obviously, you are using an extension cord to operate the saw - without it, the operation of a chain tool with an electric motor is impossible. Make sure that the extension cord is working: connect serviceable equipment through it or check it with a special device - a tester. If the problem is with the extension cord, repair of the motor or saw wiring is most likely not required.
  3. A common cause of this failure is extreme wear on the carbon brushes. They are worn out so much that the conductor breaks in them, and this destroys the electrical circuit.
  4. Check the mains cable for repairs. To do this, you need to remove the case and use the tester. We need to probe the connection of the internal nodes with the electrical plug.
  5. By the same principle, it is necessary to examine the wiring up to the saw chain start button for a malfunction.
  6. Inspect the condition of the chain, provided that the start key of the saw is clamped.
  7. If your electric saw has a soft start module, it may also need to be repaired. Make sure that the electrical circuit is not interrupted at the input and output of the module.

The saddest scenario - a breakdown is caused by a burnout of the stator / rotor windings. This malfunction is difficult to fix at home and without specialized skills, so the best solution would be to contact certified centers for professional engine repair.

Replacement of brushes on electric saw

Carbon brushes are a consumable resource, so it is important to regularly monitor their condition. If the electric saw sparks or refuses to turn on at all, this indicates the need for repair. There may be two options here:

  1. Replacement brushes. If you see that the part has worn out more than 60% of its original size, then it needs to be replaced with a new one. Otherwise, the power supply circuit may be broken and, as a result, the chain saw will not work.
  2. Brush cleaning. Abrasion of the element can cause small dust particles to fill in the gaps. If there is too much graphite, this will lead to a circuit closure and sparking.

Let's take a quick look at how carbon brushes are replaced. This process is very simple, so anyone can repair even at home:

  1. Unscrew the plastic plug (plug), which is located between the main and additional handles. You can do this with a regular slotted screwdriver.
  2. Remove the rubber seal that separates the plug from the brush.
  3. Pull out the brush. You can pick it up with tweezers or the same screwdriver.
  4. Install the new saw brush in place of the old one.
  5. Replace the gasket and tighten the plug tightly with a screwdriver.

Change the chain on the saw

Consider how to change the saw chain on a side pull saw:

  1. First, make sure you get a chain that fits your tire.
  2. Pull the protective bar towards you until it clicks. This is necessary to release the saw brake.
  3. Remove the cover from the hidden part of the saw set. Loosen the tension screw just enough to make it easy to remove the chain. Dismantle the old chain.
  4. Take your new saw chain and start placing it along the bar. The chain should be mounted on top of the sprocket, from top to bottom.
  5. After the chain is installed on the guides, use the tension screw. Do not fully tighten the chain.
  6. Replace and fix the body that hides the saw set. Adjust chain tension.

No lubrication on chain and bar

One of the reasons that the saw buzzes, but does not turn the chain, may be a lack of lubricating fluid. It is also necessary to extend the life of the chain saw. There are three reasons why lubrication problems could begin:

  1. Make sure there is enough oil in the reservoir. If users of gasoline chainsaws regularly monitor the level, because they often have to refuel the tool, some owners of electric chainsaws may forget about it.
  2. Blockage. Both the tube through which the lubricant flows, and the hole or supply filter can become clogged with debris. In this case, the repair will be a purge of this entire group.
  3. If the tank is clean, nothing interferes with the flow of lubricant and there is enough liquid itself, then the problem is in the oil pump. To solve this kind of malfunction, you have to disassemble this element and check the performance of all its parts.

Electric motor saw blade overheats

Traditionally, the overheating of an electric motor is attributed to increased load: the owners use their chain saws so intensively that their motors cannot stand it. If the engine heats up even at the slightest load, there may be several reasons for this:

  1. Your electric saw is jammed, and, more specifically, its gear gear. This happens if you do not clean the saw for a long time - it will become clogged with sawdust, which will prevent it from turning. To diagnose this malfunction, disassemble the saw to the gearbox shaft. Turn it by hand, disengaging the brake. In case of resistance, clean the gearbox - this will be enough for repair.

  2. A common cause of engine overheating is lack of lubricant on the saw chain. The problem is that without lubrication, the chain with more resistance moves along the tire, as a result of which the engine receives an increased load.
  3. The most pessimistic cause of motor overheating is a winding break. Only experts can fix this malfunction at home, so it is recommended to contact service centers for repairs.

Engine does not develop full power

The power indicator determines whether the electric saw can accelerate to the desired speed. A low value will not allow you to work with wood efficiently enough. If your electric saw does not cut at full engine power, this problem has the following reasons:

  1. Insufficient mains voltage. The source of electricity is an important part of the circuit, and if the voltage in the outlet regularly jumps, it will not be possible to ensure a stable quality of work.
  2. Jamming of the gearbox, which is caused by infrequent maintenance. Disassemble the saw and clean the engine, then continue to work.
  3. Abrasion of carbon brushes. Do not forget about the timely replacement of the brushes: this is necessary for the stable operation of the chain saw motor.
  4. Broken start key. If everything is in order with the power supply circuit and the above-mentioned elements of the electric saw, the start button may interfere with the operation of the device. This part is not repairable, but it is inexpensive (especially compared to engine parts) - just replace it.

Electric saw stops during operation

If the saw stops rotating the chain during operation, this may be caused by the following factors:

  1. End of brush life. Disassemble the chain saw and check the condition of these consumable parts: if they are too worn, replace them with new ones.
  2. Jamming of the sprocket on the saw blade. The star is the part on the "nose" of the tire that has points of contact with the chain. Due to its rotation, it sets the latter in motion. If you rarely clean the saw, the sprocket will become clogged with chips and jam. This will make it difficult for the saw to work. For repair, disassemble the saw blade and clean it. If your chainsaw has a non-separable one, treat the area around the sprocket with an all-purpose lubricant or kerosene.

  3. If you hear a distinct saw motor hum, your tool probably has a gearbox problem. In this case, the best solution is to have the repair done by a professional.

Power saw cuts crooked

Like many elements of a saw - a chain, carbon brushes - the tire tends to wear out. But how to capture this moment? This becomes especially noticeable if the chain begins to tilt to the side during operation. Because of this, sawing is uneven, sloppy. This result indicates uneven wear of the saw group. Repair involves the replacement of all its components: tires, chains, sprockets.

Replacing the spring on the electric saw

A damaged torsion spring may be the reason why your saw will not work even under minimal load (in other words, the chain on the saw will slip). Replacing the spring requires a thorough analysis of the saw, so we briefly summarize the sequence of actions:

  1. Remove the brushes from the saw.
  2. Remove the circlip from the star. Take off the star.
  3. Loosen the screws securing the gearbox housing. Remove the case.
  4. Remove the auxiliary handle.
  5. Disconnect the mechanical housing from the electrical housing.
  6. Remove the saw brake by removing all fasteners holding it in place.
  7. Remove the base holding the gearbox gear.
  8. Remove the oil tank.
  9. Remove the small gear connected to the large reduction gear.
  10. With a little physical effort, remove the large gear with your hands.
  11. Unscrew the retaining nut of the gear reduction gear.
  12. Remove bearing and gear.
  13. Prying off the old torsion spring with a screwdriver, remove it.
  14. Put a new one in its place.
  15. Assemble the saw following the reverse sequence of the algorithm.

Replacing the saw bar

One of the reasons for the failure of the electric saw is the wear of the bar on which the chain is attached. You can dismantle the old and install a new tire with your own hands, and then we will look at how:

  1. Buy a new tire. When purchasing, consider the length of the bar, the width of the groove and the pitch of the chain - according to these parameters, it must correspond to its "predecessor".
  2. Remove the chain. To do this, reduce the tension to the minimum.
  3. Remove the old tire. Remove the nut that secures it to your chainsaw.
  4. Lubricate the new tire. For these purposes, special holes are provided on it. You can also soak the tire overnight in engine oil.
  5. Pull the chain over the new bar. Remember to take into account the direction of chain movement.
  6. Install the bar and chain on the saw.
  7. Tighten the nut that secures the tire with your fingers.
  8. Tighten the saw chain using the adjusting bolt or tensioner.
  9. Tighten the nut on the tire until it stops.

How to put the chain on the saw

One of the reasons why the chain on the saw flies off may be the incorrect installation of the chain on the saw bar. Earlier we already mentioned the issue of changing the chain, but now we will touch on the topic of putting it on the tire in more detail.

First of all, make sure you protect yourself: put on thick protective gloves. After removing the old chain, take a new one and start laying it on the guide gradually so that it is clearly fixed in the grooves. This is necessary to prevent injury during operation.

It is important to pay attention to the fact that the teeth must be located in the direction of the chain movement along the bar. Often there are marks on the saw sets and the saw itself, allowing you to correctly determine the direction of rotation.

How to tension the chain on the electric saw

If your saw chain is slipping off, you may have pulled the chain too loose on the saw bar. Proper chain tension will extend saw blade life. It is important to maintain a certain degree of tension and regularly maintain it.

There is a way to quickly check if the saw chain is well tensioned on the bar: in the center of the top of the bar, select the tooth and pull it up. As a result, if the chain is rotated by hand, a third of the point should remain on the guide bar.

Safety measures

A power saw, like any other cutting chain tool, is extremely dangerous to operate. We recommend that you follow a number of rules so that you do not get hurt during operation and do not shorten the life of the saw:

  1. Work should be carried out in all personal protective equipment: glasses, gloves, headphones. We also advise you to wear closed clothes and tight shoes.
  2. If the saw is spinning or showing other signs of malfunction, stop the operation. Get rid of the problem yourself or use a repair service.
  3. Maintain the saw in a timely manner: check the condition of the carbon brushes, add lubricant to the reservoir, and clean the saw from heavy dirt.
  4. Carry out all repair work only with the electric saw motor disconnected from the mains.
  5. When transporting, be careful: install a protective cover on the bar with the chain.
  6. If possible, use repair services only from authorized service centers. The same applies to replacement parts and consumables - the manufacturer of the electric saw can only guarantee compatibility with their products.
