From understanding the different sizing systems to choosing the right tire size for your ATV and even some tips and tricks, we’ve got you covered.
Metric Sizing System
The metric sizing system is one of the most commonly used when it comes to ATV tire sizes. It is denoted by three numbers separated by slashes, such as 25/10-12. The first number represents the overall height of the tire in inches, the second number refers to the tire width in inches, and the third number indicates the diameter of the wheel on which the tire will be mounted. So, in the example of 25/10-12, the tire has a height of 25 inches, a width of 10 inches, and will fit a 12-inch diameter wheel.
Alpha-Numeric Sizing System
Another sizing system you might come across is the alpha-numeric system. This system uses a combination of letters and numbers to denote the tire size. For example, you may see a tire size like AT25x10-12. The “AT” in this case stands for “All Terrain”, which indicates the tire’s use. The numbers following the “x” represent the tire’s height and width, while the last number represents the wheel diameter.
Reading the Tire Size Code
It’s important to understand how to read the tire size code to ensure you’re getting the right tire for your ATV. The first step is to decipher whether the sizing system being used is metric or alpha-numeric. Once you know the system, you can easily determine the tire’s height, width, and wheel diameter by looking at the numbers or letters provided.

How to Measure Tire Width
Measuring the tire width is relatively straightforward. You’ll need to measure the distance from one side of the tire’s sidewall to the opposite sidewall using a measuring tape or ruler. This measurement will give you the tire’s overall width.
Common Aspect Ratios
The aspect ratio of a tire refers to the ratio between the height and width of the tire. This ratio is often expressed as a percentage. For example, if a tire has an aspect ratio of 75, it means that the tire’s height is 75% of its width. Understanding aspect ratios can be helpful when comparing different tire options and their visual profiles.
