- Check the driver’s door jamb placard for "TIRE SIZE" and recommended cold inflation pressure.
- Consult the owner's manual or the tire and loading information label for the recommended sizes and load index.
- Inspect the tires currently on the vehicle and read the size printed on their sidewalls (e.g., P235/75R15).
- If you carry a spare, verify whether it matches the main tires or is a temporary spare with a different size.
Following these steps will help ensure you maintain correct speedometer readings, handling, and safety with tire changes.

Correct tire size affects ride quality, gearing, and safety. If you plan to switch sizes (for example, larger or smaller tires), consider consulting a tire professional to adjust for speedometer accuracy, ABS, and tire clearance.
