Understanding ATV/UTV Tire Sizing
It's important to know the size of your ATV/UTV tires when you are considering replacing the original equipment tires. As with regular passenger vehicles and light trucks, having the right size tire is important for performance and handling.
ATV/UTV Sizing Explained
While an ATV/UTV tire size looks similar to passenger tire sizes, they are not quite the same.
- 25 = the overall height of the tire in inches at its proper operating air pressure.
- 10 = the width of the tire in inches when inflated to the proper operating air pressure.
- D = the tire's construction type.
- 12 = the wheel size.
ATV/UTV tires have a bias ply or a radial construction. The D, as in this example, has a bias ply construction. If it has a R listed in the tire size, it is a radial construction.
Changing Your ATV/UTV Tire Size
It is very common to increase your tire size when replacing the original equipment tires. Using a larger tire size can increase ground clearance and give your ATV or UTV a more aggressive appearance. However, you should be very careful to maintain proper spacing between the tires, suspension, and the fenders.
When you change tire sizes, the increase in diameter and the possible increase in weight and width may cause mechanical issues. If you choose to go to a larger tire size, it is suggested that you not increase the height or the width by more than one inch. Size increases greater than this can require adjustments to your ATV or UTV suspension. Modifications as drastic as this can also cause serious changes to the handling and performance of your ATV or UTV.
