ATV tire explaination: ATV tires are listed in a set of three numbers, generally separated by dashes (25-10-12), or by an ‘x’ (25x10x12) or a combination of the two: 1st Number = The overall tire height when inflated (Ex. 3rd Number = The rim or wheel diameter (Ex. 25×10-12 is 12″ in diameter).
All ATV Tire sizes consist of 3 sets of numbers generally separated by dashes (ex. 25-8-12), forward slashes (ex. 25/8/12), or with an x (ex. 25x8x12). 1st Number = The overall height of the tire. (ex. 25×8-12 tire is 25″ tall.)
What do the numbers mean for an ATV tire size? Understanding ATV tire sizes. Inch size is the most widely used measurement in ATV tires. In the size 25 8.00-12, the meaning of the numbers is as follows: 25 – The overall height of the tire when mounted and inflated. 8.00 – The overall width of the tire when mounted and inflated. 12 – The diameter of the wheel this tire will mount to.
How do you size an ATV tire? Shown here is an example of ATV tire sizing. All ATV Tire sizes consist of 3 sets of numbers generally separated by dashes (ex. 25-8-12), forward slashes (ex. 25/8/12), or with an x (ex. 25x8x12). 1st Number = The overall height of the tire. (ex. 25×8-12 tire is 25″ tall.) 2nd Number = The overall width of the tire. 3rd Number = The rim diameter.
What does the are mean on an ATV tire? This tells you the diameter of the rim for the tire on your ATV. In the example, “26X10-12,” the rim size is 12. Some numbers on ATV tires will have an “R” between the second and third number. The “R” simply means radial construction.
What is the width of an ATV tire? Notice the second number in the series of three. This number corresponds to the width of the tire or how fat the tire measures. In our example, “26X10-12,” the width of the ATV tire is 10 inches. Find the third number.

33-inch tires work well with rims that measure 15 or 16 inches in width, while 35-inch tires should only be used with rims that are at least 17-inches wide.
The current tire on my quad is a 22x11x10. The smallest size these tires have is the 22x12x10. 22 = The overall height of the tire when mounted and inflated to recommended air pressure. In this example, the tire is 22 inches tall. 12 = The overall width of the tire when mounted and inflated to recommended air pressure.
25×11-12. The ATV tires within this category are all available in the selected size; 25×11-12. The numbers 25-11-12 represent the dimensions of the tire. The first number is the height, the second number is the width & the third number is the diameter of rim that it will fit on.

B: TIRE WIDTH The three-digit number following the letter is the tire’s width (from side to side, looking at the tire head on) in millimeters. It’s the height of the sidewall measured from wheel rim to top of the tread, expressed as a percentage of tire width. In other words, it’s sidewall height divided by tire width.
A 305/70/16 is a 32.8 (~33) by 12.00 inch tire.
Obviously, you will need a certain kind of tire depending on how you use your vehicle. Due to this, a 235 tire might not be better than a 225 tire, or vice versa, but depending on your situation, one tire might serve you better than the other.
This number indicates that your tire has a width of 265 millimeters. 70. This number means that your tire has an aspect ratio of 70%. In other words, your tire’s sidewall height (from the edge of the rim to the tire’s tread) is 70% of the width. In this case, the sidewall height works out to be 185 millimeters.

When replacing the tires on your ATV, you must choose from a wide range of tire sizes. In this post, you’ll find information about the most common ATV tire sizes, a few real-life examples, how to read ATV tire sizes, and how you can be confident you choose the right size for your ATV.
ATV tire sizes are indicated on the tire sidewall and are typically given in one of two different sizing formats.
Out of the two, the imperial format in inches is most common in ATV tires. Metric sizing is more common in car tires, but now and then, you’ll stumble across an ATV tire with metric sizing.
ATV tire measurements are always with a tire that is inflated to the recommended tire pressure.
The easiest way to tell you’re dealing with a metric tire size is the dash “/” separating the first and second number rather than a hyphen “-“.
Another giveaway is the larger numbers. 100 millimeters equals 25.4 inches, so the numbers on a metric-sized tire are much higher than on a standard-sized tire.
The three numbers in the standard imperial tire sizing format represent three critical tire dimensions.
For example, a 26X11-14 size tire is 26 inches high and 11 inches wide and will mount to a wheel or rim that is 14 inches in diameter.
A Letter “R” between the second and third numbers indicates a radial construction tire, while a hyphen “-” indicates a bias ply tire.
The metric tire size format is not as self-explanatory as the standard imperial format.
To make matters worse, it doesn’t only use millimeters but also inches, percentages, and letters.
Luckily you are much less likely to come across a metric-sized ATV tire. If you do, here is how to know what size it is.
For example, a 215/80-14 size tire is 215mm wide, has a sidewall height of 172mm (80% of 215mm), and will mount to a wheel or rim that is 14 inches in diameter.
A Letter “R” between the second and third numbers indicates a radial construction tire, while a hyphen “-” indicates a bias ply tire.
An average ATV tire is 25 to 27 inches tall and 7 to 10 inches wide, with a wheel diameter of 10 to 12 inches. Sport quad tires are usually slightly smaller than average, while mud tires are generally larger than standard tires.
In everyday speech, ATV tires are often referred to only by the tire’s outer diameter. Typical tires sizes can be categorized by ATV type :
Note that the front tires are usually one or two inches narrower than the rear tires.

At a glance, most ATV tires look the same. But when you go to a tire shop in real life or online, you soon realize there are almost endless sizes to choose from. But why does it have to be this way? Why don’t all ATVs use the same size tire?
The wide range of available ATV tire sizes reflects the versatility ATVs are well-known for and the wide range of conditions they go in.
Different riding applications and riding conditions require different tire sizes for optimal performance.
For instance, when riding in soft and muddy conditions, you need a larger tire so you won’t sink in as much.
However, bigger tires are generally much heavier than smaller ones, negatively impacting acceleration and handling. That is why race quads typically use smaller tires.
ATV race tracks usually have medium to firm surfaces of dirt or gravel that don’t require massive tires not to get stuck. Winning the race requires a lightweight tire that spins easily so that as much as possible of the engine power gets converted into speed.
And finally, for most ATV riders, including those that use the bike for utility tasks, trail riding, or hunting, it’s all about finding a happy medium. That is why most ATV tires are from 25 to 27 inches tall.

You cannot choose any size tire and expect good results.
Your best bet would be to choose the same size as printed on the sidewall of your old ones.
Make sure to cross-reference the numbers against those specified in the user manual to ensure nobody has previously changed to a different-size tire.
You can measure and compare to ensure your chosen tire fits the wheel/rim.
Alot of people wonder whether they can install bigger tires on their ATVs. There are several reasons why people want to upgrade to beefier tires:
Generally, you can install one to two inches larger diameter tires without modifying the ATV. Larger tires require various modifications to prevent tire rubbing, gear ratio issues, loss of torque, and premature belt wear.

The numbers written on the side of the rubber tire can tell the owner of the ATV everything that interests him. And if you are for some If you don't know what these mysterious numbers mean, then you can be mistaken when choosing the next set of tires. But tires directly determine whether it will go technique further or not. So, in this article you will close all the questions on about the decoding of size ATV tire .
All tires have their own basic parameters - this is the width, height and diameter.
The value of these parameters is mainly measured in inches. Exists two units:
1) If you have ATV, then this is for you. English version is the most common number system that is used when determination of tire dimensions on ATVs. All measurements here are in inches. (1 inch equals 2.54 cm). For example, the size indicated in English classification looks like this - 25x8x12 . Let's take a closer look at the meaning of each digit:
- The first digit 25 shows the height of the tire in inches;
- The second digit 8 indicates the width of the tire in inches;
- The last, third digit 12 indicates the diameter of the wheel disk, it is also measured in inches. Disc diameter on each ATV can be different. Therefore, be careful before you buy tires for ATV, see what regular disks are installed on your vehicle.
And a very important point worth noting. Often our customers ask themselves: “If I have a tire size of 20x10x10, can I put instead of them 20x11x10? The answer is yes.
First, you can put rubber on regular wheels with a size exceeding 1 inch in height and width. Secondly, if you want tires even wider, then for this you will need to buy other disks. But again, there are limitations. On discs of other diameters, you can install rubber, the largest is only 2 inches in height and width.
These two rules must be strictly observed, otherwise, if you try to put tires of an unacceptably large size, this may adversely affect on a quad bike. After all, the rubber will be larger and, accordingly, heavier, which does not fit the technical parameters of the ATV. In production ATVs take into account all the characteristics, so manufacturers of ATV equipment I don't recommend using bigger tires at all. But if you do decided to increase the size of tires, call our toll-free number, we we will help.
2) Also there is another version - metric . Here the dimensions are indicated in percentage and millimeters. For example, size specified according to the metric classification - 205/80 Rx12 .
Such designations are usually used on automobile tires. Let's see what's what:
- The first digit of 205 shows the total tire width in millimeters. Converting this value to inches, we will just get the number 8 (in the English version is 8 inches wide).
- The second digit 80 indicates the ratio of the height of the tire to its width, measured as a percentage. After doing some mathematical manipulations, we get the number 25 (in the English version, the height is equal to 25 inches).
- The number 12, as in the English version, shows the size disk in inches.
- Well, the letter R means that our tire is radial.
The most important thing to remember from the article is that it is not recommended to install tires of huge sizes that do not correspond to the parameters your ATV . If you want to change the tires on your vehicle, give us a call. we will help.

An ATV is perhaps one of the most versatile vehicles.
On it you can go hunting or fishing, take part in high-speed races or just go with your family to nature. Depending on the purpose for which the ATV will be used, a suitable model is selected.
An important factor is the choice of rubber, since the efficiency and safety of using an ATV depends on it.
When choosing tires for ATVs, you should be guided not only by personal needs, but also take into account your driving style, and also in what conditions the “iron horse” will be used. All tires for an ATV are divided into two types - diagonal and radial. Each of them is designed for driving in a certain area. Bias tires are the most popular, as they do an excellent job of overcoming fords, mud and swamps. Radials are designed for high speed driving on hard surfaces, so they are usually used on racing models.
One of the most important details when choosing a quad tire is the tread pattern. And this is far from a design "trick", as many believe.
It depends on him in what conditions it will be possible to use the ATV. Based on this, all tires are divided into the following types:
for sand - have a bladed tread that provides excellent grip on sandy terrain;
Mud - equipped with deep herringbone tread to avoid towing when hit in mud;
sporty - have a flat surface with small protrusions to guarantee maximum stability on a hard road surface;
universal - their tread has a small pattern that provides excellent grip on any terrain;
winter - have a special tread pattern, and can also be additionally equipped with spikes and chains.
Quad tires are usually used in two systems of sizes - English and metric. English looks like this: 25x8-12, where 25 is the height of the tire in inches, 8 is its width, 12 is the diameter of the disk.
For us, the metric system is more convenient, which has the following form: 205 / 80R12, in this case, the dimensions are in millimeters.
