How It Works
Select your vehicle's make, model, and year range to see the original equipment (OEM) tire size installed by the manufacturer.
The tool also shows popular upgrade sizes that are known to fit your vehicle, along with dimension comparisons so you can see exactly how much larger or smaller each option is.
Overall diameter, width, sidewall height, and circumference are calculated using standard tire math formulas from the metric tire size notation.
How to Read a Tire Size
A tire size like P265/70R17 breaks down as:
- P — Passenger tire (LT = Light Truck)
- 265 — Section width in millimeters
- 70 — Aspect ratio (sidewall height is 70% of width)
- R — Radial construction
- 17 — Rim diameter in inches
Flotation sizes like 33x12.50R15 use inches: 33" overall diameter × 12.5" width on a 15" rim.
Frequently Asked Questions
How do I find the OEM tire size for my vehicle?
The easiest way is to check the driver's door jamb sticker, your owner's manual, or use our vehicle lookup tool above. The door jamb sticker shows the manufacturer-recommended tire size, load rating, and inflation pressure for your specific vehicle.
Can I put a different tire size on my vehicle?
Yes, but you need to stay within a safe range. Generally, you can go up or down about 3% in overall diameter without issues. Larger changes may require modifications like a lift kit, fender trimming, or a speedometer recalibration. Our upgrade suggestions above are all proven fitments for your vehicle.
What happens if I use the wrong tire size?
Using the wrong tire size can cause rubbing on fenders or suspension components, inaccurate speedometer readings, reduced fuel economy, voided vehicle warranty, and potential safety issues. Always verify fitment before purchasing new tires.
Do I need to change my wheels to upgrade tire sizes?
It depends on the upgrade. Some larger tire sizes fit your stock wheels, while others require a different wheel diameter or width. Our tool shows which upgrades match your current rim size and which require new wheels.
