The sizes and/or speed ratings listed may vary slightly from the specified OE size shown on the vehicle placard. Your local tyre dealer, as a trained professional, will provide the required assistance to install the listed tyre by:
- Notifying the owner if the replacement tyres are different in speed rating than the OE tyres and the maximum speed capability of the vehicle is limited to the lower speed rated tyres.
- Determine if any inflation pressure adjustments are necessary with the alternate listed size.
