Important Notes
Tread patterns must often be tuned to accommodate different tire widths. While tires reserved will match your order's specifications, photos used only represent typical sizes.
When searching by tire size alone, please be aware that the displayed results may not be applicable (or recommended) for your vehicle due to several factors (including but not limited to speed rating, load capacity, etc.) To view recommended tire options for your vehicle click "Find Tires By Vehicle" and enter the required information.
The sizes and/or speed ratings listed may vary slightly from the specified OE size shown on the vehicle placard. Your Continental Tire Agent, as a trained professional, will provide the required assistance to install the tire listed by:
- Notifying the owner if the replacement tires are different in speed rating than the OE tires and the maximum speed capability of the vehicle is limited to the lower speed rated tires.
- By confirming that the tire has adequate maximum load capacity.
- Determine if any inflation pressure adjustments are necessary with the alternate listed size.
*Installation is: mount, balance, and TPMS reset. Tire tax or disposal fees are extra
