How to confirm the exact tire size on your car
To ensure you have the correct size, start with the car’s own labeling and official documentation. Use the following steps to confirm without guesswork.
- Check the driver’s door jamb placard for the recommended tire size and inflation pressure.
- Inspect the sidewall of your current tires for the size code (for example, 195/65R15) if you’re replacing like-for-like.
- Consult the owner’s manual or contact a Honda dealership or a trusted tire retailer for the official specifications by trim and market.
When replacing tires, also match or exceed the OEM load rating and speed rating to maintain safety and performance.
Notes for upgrading or changing wheel sizes
Upgrading to different sizes can affect handling, speedometer accuracy, and braking performance. Always consult a tire professional to ensure compatibility with wheel width, offset, suspension clearance, and ABS calibration.
- Ensure the overall diameter remains within a small tolerance of the OEM to avoid speedometer error and traction control issues.
- Verify that the chosen tire width and aspect ratio fit within the wheel wells and do not rub on arches or suspension components.
- Respect the vehicle's load and speed ratings to maintain safety margins.
