GM Service Manual Online
For 1990-2009 cars only

Caution: Driving with more than one compact spare tire at a time could result in loss of braking and handling. This could lead to a crash and you or others could be injured. Use only one compact spare tire at a time.

The compact spare tire was fully inflated when the vehicle was new, it can lose air after a time. Check the inflation pressure regularly. It should be 60 psi (414 kPa).

After installing the compact spare on your vehicle, you should stop as soon as possible and make sure your spare tire is correctly inflated. The compact spare is intended to perform well at speeds up to 50 mph (80 km/h), so you can finish your trip and have your full-size tire repaired or replaced where you want. Replace your spare with a full-size tire as soon as you can.

Notice: When the compact spare is installed, do not take the vehicle through an automatic car wash with guide rails. The compact spare can get caught on the rails which can damage the tire, wheel and other parts of the vehicle.

Do not use your compact spare on other vehicles.

Do not mix your compact spare tire or wheel with other wheels or tires. Keep your spare tire and its wheel together.

Notice: Tire chains will not fit the compact spare. Using them can damage the vehicle and can damage the chains too. Do not use tire chains on the compact spare.
