NOTES
- If a 4x4 Tire is marked 31/10.5-15 or alike; 31 is approximate height in inches (but it will show in the Width drop-down) and 10.5 is approximate width in inches(but it will show in the Profile drop-down).
- Speedometer reading will differ by the same % as the % change in Tire height at the same rpm.
- A Bigger Tire: You will be traveling faster than your speedometer reading.
- A Smaller Tire: You will be traveling slower than your speedometer reading.
- It is always recommended to use the correct OEM Tire Size for your vehicle, have a look at your door tags or contact the manufacturer.
- Keep all of the above in mind if you want to change your Tire Size.
