Tire Mixing

It is recommended that all four tires be of the same size, load index, speed rating, and construction (radial, non-radial). In some cases, the vehicle manufacturer may require different-size tires for either the front or rear axles. Check your owner’s manual for information.

Speed-rated tire – If the vehicle’s tire placard and/or owner's manual specifies speed-rated tires, the replacement tires must have the same or higher speed rating to maintain vehicle speed capability.

Four-wheel-drive (4WD) and all-wheel-drive (AWD) vehicles – If no instructions for tire mixing appear in the vehicle owner's manual, follow these guidelines:

• DO NOT mix tire sizes. All four tires must be marked with the same tire size, unless otherwise specified by the vehicle manufacturer. This also applies to winter/snow tires.
• DO NOT mix radial and non-radial tires. All four tires must be either radial or non-radial.
• DO NOT mix tread pattern types, such as all-terrain and all-season.
