How Do I Find My Tire Size?

May 22, 2023 May 22 2023

When looking to purchase ATV or UTV tires, you will have to know your tire size. To find your tire size, you can look on the sidewall of your tire for a specific series of numbers and letters. This series indicates the tire’s width, aspect ratio, construction, wheel diameter, and load rating. 

There are two main ways that tire sizes will show: standard and metric. Standard is what most ATV/UTV tires will display. Metric is what is displayed for most passenger tires. 

Standard Tire Sizing 

A typical ATV or UTV tire will show the size as three numbers, separated by the letter “x” or one letter “x” and one “-“. 

Below are examples of what the tire size information might look like in standard sizing:

29x11x14 or 29×11-14

Here is a breakdown of what each part of the tire size means:

  • 29: The height of the tire when mounted and inflated to recommended air pressure.
  • 11: The width of the tire when mounted and inflated to recommended air pressure.
  • 14: The diameter of the wheel that this tire will mount to.

Metric Tire Sizing 

Here’s an example of what the tire size information might look like:  
205/40R17 94T 

Here is a breakdown of what each part of the tire size means: 

  • 205: The three-digit number after the letter indicates the tire’s width in millimeters.
  • 40: The two-digit number after the slash indicated the tire’s aspect ratio or the ratio of the tire’s height to its width. In this case, the tire’s height is 40% of its width.
  • R: The letter “R” indicates that the tire has radial construction.
  • 17: The two or three-digit number after the wheel diameter indicated the tire’s load rating, or how much weight the tire can support.
  • 94: The two or three-digit number after the wheel diameter indicated the tire’s load rating, or how much weight the tire can support.
  • T: The final letter in the tire size indicates the tire’s speed rating, or the maximum speed the tire can handle.

The format of the tire size may vary slightly depending on the brand and model of the tire, but the information should generally be the same. 

Things To Know 

Before switching out your tires and hitting the trails, there are a couple of other things you should know: 

  • Make sure the tire’s wheel diameter matches your actual wheel diameter. 
  • Choose the tire made for your ride style, specifically designed for conditions like mud, rock, hardpack/turf, sand, racing, and more. 
  • If you find yourself on loose surfaces and need more traction, a wider tire will help you get the grip you need.
