GM Service Manual Online
For 1990-2009 cars only

The vehicle, when new, had a fully-inflated spare tire. A spare tire may lose air over time, so check its inflation pressure regularly. See Inflation - Tire Pressure and Loading the Vehicle for information regarding proper tire inflation and loading your vehicle. For instruction on how to remove, install or store a spare tire, see Removing the Flat Tire and Installing the Spare Tire and Storing a Flat or Spare Tire and Tools .

After installing the spare tire on your vehicle, you should stop as soon as possible and make sure the spare is correctly inflated.

The spare tire does not have a Tire Pressure Monitor System sensor. You may get a low pressure warning light. See Tire Pressure Monitor Operation . Have the damaged or flat road tire repaired or replaced as soon as you can.

Do not mix tires and wheels of different sizes, because they will not fit. Keep your spare tire and its wheel together.
