If you ever replace your tires with those not having a TPC Spec number, make sure they are the same size, load range, speed rating and construction type (bias, bias-belted or radial) as your original tires. CAUTION: (Continued) If your vehicle has 17 inch road tires (those originally installed on your vehicle) it is all right to drive with the 16 inch spare tire that came with your vehicle. When new, your vehicle included a spare tire and wheel assembly with the same overall diameter as your vehicle's road tires and wheels. Because this spare tire was developed for use on your vehicle, it will not affect vehicle handling or cause damage to your vehicle. CAUTION: Mixing tires could cause you to lose control while driving. If you mix tires of different sizes or types (radial and bias-belted tires), the vehicle may not handle properly, and you could have a crash. Using tires of different sizes may also cause damage to your vehicle. Be sure to use the same size and type tires on all wheels. CAUTION: (Continued) CAUTION: If you use bias-ply tires on your vehicle, the wheel rim flanges could develop cracks after many miles of driving. A tire and/or wheel could fail suddenly, causing a crash. Use only radial-ply tires with the wheels on your vehicle. 6-53
