Understanding OEM Tire Sizes

Every vehicle leaves the factory with a specific tire size chosen by the manufacturer to optimize handling, ride comfort, fuel economy, and safety. This is called the OEM (Original Equipment Manufacturer) tire size.

When it's time to replace your tires, you have three options:

Plus Sizing Guidelines

When upgrading to larger wheels, keep the overall tire diameter within ±3% of the original size to avoid speedometer errors and clearance issues:

Frequently Asked Questions

Why does my vehicle have different front and rear tire sizes?
Some performance and luxury vehicles use staggered fitments—wider tires on the rear axle for better traction and handling. This is factory-designed and should be maintained when replacing tires. Use our rotation calculator for staggered fitment advice.
Can I use winter tires in a different size?
Yes. Many drivers choose a narrower winter tire with a taller sidewall (minus sizing) for better snow traction and to protect expensive alloy wheels. As long as the overall diameter is close to stock, this is a safe and common practice.
What does the load index mean?
The load index is a numerical code indicating the maximum weight each tire can support when properly inflated. For example, a load index of 94 means each tire can carry 1,477 lbs. Never install tires with a lower load index than your vehicle requires.
What does the speed rating mean?
The speed rating indicates the maximum speed a tire can sustain under its rated load. Common ratings: H = 130 mph, V = 149 mph, W = 168 mph, Y = 186 mph. Always match or exceed your vehicle's required speed rating.
What if my vehicle isn't in the database?
Our database covers the most popular vehicles sold in the US from 2018-2026. If your vehicle isn't listed, check your driver's door jamb sticker or owner's manual for the factory tire size. You can also use our Tire Size Comparison tool to evaluate alternative sizes.
