How to use this record
The calculator compares nominal wheel and tire position with this OEM baseline. It does not calculate fender, suspension, brake, steering, or loaded clearance. Tires with the same printed size can differ by manufacturer. Confirm applicability for the exact year, market, trim, and package, then measure or test-fit before buying.
