Selecting New Tires

When selecting new tires, make sure they meet the requirements of your UTV and its expected usage. Always refer to the owner’s manual and tire manufacturer’s website for recommended tire size, construction, performance and suggested air pressure.

UTV Tire Measurements

UTV tires are commonly measured by Height x Width x Inner Wheel Diameter (HxWxID) in inches.

• Just because this tire says 25 on it doesn't mean it will measure exactly 25 inches tall. There are so many variables that can affect your tire height so don't be surprised if they don't measure 100% accurate but they should be within reason, give or take about 3/4 inch either way. Air pressure, age of tire, ply rating, tread wear, weight of vehicle, width of rim and brand of tire are all factors that come into play in the overall height of your tires
• The 10 (or whatever the middle number is) is the width of the tire, just like the height, just because your tire says 10 on it doesn't mean it will measure exactly 10 inches wide. The width of your rim has a huge affect on how wide your tire will measure after you install it. There are other factors that can affect the width just like the height, so don't be surprised if your tire says 10 in the middle number but it only measures 9.5 inches wide.

Term definitions:

• Radial: Radial constructed tires utilize both ply and breaker (or belt) cords. The ply cords extend from bead to bead at approximately 90 degree angle to the centerline of the tire. The breaker (or belt) cords are placed on top of the ply cords across the width of the tire. Advantages: Adding breaker (or belt) cords results in a stiffer carcass which helps provide a longer tread and tire life, better steering control and handling, overall smoother ride and ride comfort, and higher tread puncture resistance.
• Bias: Bias tires typically have the ply cords that extend diagonally from bead to bead at a range of 30 to 60 degree angles from the centerline. Each successive ply is laid at an opposing angle, forming a criss-cross pattern. Advantages: The design allows the entire tire body to flex easily, giving a comfortable ride on rough surfaces.

UTV Wheel Sizing and Offset 

To determine the diameter of a wheel: Measure the width of the bead area of the wheel (not the outer rim). In the diagram above, the diameter measures 12 inches.

To determine the offset and width of a wheel: Measure from the center weld to the center of the tire bead area on both sides of the wheel. The outer measurement will be the one with the valve stem. The offset of a wheel is stated by reading the measurement of the inside first, then the measurement of the outside (valve stem side). For example: In the diagram above, the offset is 5+2; meaning the inside half of the wheel measured 5 inches, and the outside (valve stem side) measured 2 inches. Add these 2 numbers together to find the total width of the rim (7 inches).

Note: If the rim has a tire on it, usually the tire will have the rim diameter imprinted on it (8", 9", 10"...). You can also measure the rim from inside using the diagram above and getting the measurements as close as possible.

Warning

The charts and info on this page do not imply interchangeability. Consult your machine’s manual to determine correct replacements, clearances, compatibility and stability, load-bearing capacity, speed rating, radial vs. non-radial recommendations, pattern and tread compound requirements, inflation recommendations and front-to-rear tire matching. WRONG SELECTION CAN RESULT IN TIRE FAILURE OR LOSS OF CONTROL WITH SERIOUS INJURY OR DEATH
