How to Find the OEM Tire Size on Your ATV or UTV

Finding the correct OEM tire size for your ATV or UTV is essential for maintaining proper performance, handling, and reliability. The OEM (Original Equipment Manufacturer) tire size is the size that came installed from the factory and is the best reference point when replacing worn tires or considering an upgrade.

Below are the most reliable ways to identify the OEM tire size for your machine.

1. Check the Tire Sidewall

The quickest way to find your OEM tire size is to look directly at the sidewall of your current tires.

Most ATV and UTV tires display the size in a format similar to:

This breaks down as:

• 25 – Overall tire height (in inches)

• 10 – Tire width (in inches)

• 12 – Wheel diameter (in inches)

If your tires are original and have not been changed, this number represents your OEM tire size.

Tip: Check both front and rear tires, as many ATVs and UTVs use different sizes.

2. Look in the Owner’s Manual

Your owner’s manual lists the factory tire sizes for both front and rear wheels.

The manual will typically show:

• Front tire size

• Rear tire size

• Recommended tire pressure

If you don’t have a physical copy, most manufacturers provide downloadable manuals on their official websites.

3. Check the Manufacturer’s Vehicle Specifications

OEM tire sizes are also listed in the vehicle’s technical specifications.

You can find these by:

• Visiting the manufacturer’s website

• Searching by make, model, and year

• Checking dealer listings or spec sheets

This is especially useful if your current tires are worn, unreadable, or previously replaced.

4. Inspect the VIN or Compliance Label

Many ATVs and UTVs have a compliance or information label located:

• Under the seat

• On the frame

• Inside the engine bay

This label often lists factory specifications, including tire size, wheel size, and recommended pressure.

5. Confirm Before Upsizing

If you plan to run a different tire size than OEM, always start by knowing the factory size.

OEM size helps you:

• Maintain correct gear ratio

• Avoid rubbing issues

• Preserve steering and suspension performance

Upsizing may require wheel offset changes, suspension modifications, or lift kits.

Even small size changes can affect how your ATV or UTV performs.
