For front or rear wheel drive vehicles, we recommend mounting the new tires on the rear axle, in order to prevent an oversteer condition. When purchasing a single new tire, it should be paired on the rear axle with the tire having the greatest remaining tread depth . When radial tires are unavoidably used with bias-ply tires on the same vehicle (not recommended), the radial tires must ALWAYS be placed on the rear axle. NEVER mix radial & bias-ply tires on the same axle.

For 4-wheel drive vehicles, if no instructions for tire mixing appear in the vehicle owner's manual, adhere to the following guidelines:
Do not mix sizes --all four tires must be branded with the same tire size.
Do not mix radial & bias-ply tires.
Outside circumference of all four tires should be within one & one-half (1-1/2) inches of each other.
Do not mix tread patterns such as all-terrain & all-season.
