Vehicle Service and Care GM recommends replacing tires in sets of four. This is because uniform tread depth on all tires will help keep the vehicle performing most like it did when the tires were new. Replacing less than a full set of tires can affect the braking and handling performance of the vehicle. See Tire Inspection and Rotation on page 9-53. 9-55 CAUTION (Continued) { CAUTION Mixing tires could cause you to lose control while driving. If you mix tires of different sizes, brands, or types (radial and bias-belted tires), the vehicle may not handle properly, and you could have a crash. Using tires of different sizes, brands, or types may also cause (Continued) damage to the vehicle. Be sure to use the correct size, brand, and type of tires on all wheels. It is all right to drive with the compact spare temporarily, as it was developed for use on the vehicle. See Compact Spare Tire on page 9-70. Vehicles that have a tire pressure monitoring system could give an inaccurate low-pressure warning if tires not recommended for the vehicle are installed. Tires that do not match the original equipment tires could give a low-pressure warning that is higher or lower than the proper warning level you would get with original equipment tires. See Tire Pressure Monitor System on page 9-48. The vehicle's original equipment tires are listed on the Tire and Loading Information Label. See Loading the Vehicle on page 8-32, for more information about the Tire and Loading Information label and its location on the vehicle. { CAUTION If you use bias-ply tires on the 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 the vehicle.
