GM Service Manual Online
For 1990-2009 cars only

If a tire goes flat, avoid further tire and wheel damage by driving slowly to a level place. Turn on the hazard warning flashers.

Caution: Changing a tire can be dangerous. The vehicle can slip off the jack and roll over or fall on you or other people. You and they could be badly injured or even killed. Find a level place to change your tire. To help prevent the vehicle from moving:

  1. Set the parking brake firmly.
  2. Put the shift lever in P (Park).
  3. Turn off the engine and do not restart while the vehicle is raised.
  4. Do not allow passengers to remain in the vehicle.
To be even more certain the vehicle will not move, you should put blocks at the front and rear of the tire farthest away from the one being changed. That would be the tire, on the other side, at the opposite end of the vehicle.

Object Number: 809762  Size: A2

To remove a center cap, use the wrench to pry gently at the notch. Do not use a tool that is narrower than the wrench to pry at this notch. Then pry off the cap.

Removing the Wheel Covers

If the vehicle has wheel covers, be sure to use a wheel wrench to begin the process of loosening the plastic wheel nut caps.


Object Number: 809766  Size: A3

Once the plastic nut caps have been loosened with the wheel wrench, finish loosening them with your fingers.

Then, using the flat end of the wheel wrench, pry along the edge of the wheel cover until it comes off. Be careful; the edge may be sharp. Do not try to remove the cover with your bare hands.

  8. Caution: Getting under a vehicle when it is jacked up is dangerous. If the vehicle slips off the jack you could be badly injured or killed. Never get under a vehicle when it is supported only by a jack.

    Caution: Raising your vehicle with the jack improperly positioned can damage the vehicle and even make the vehicle fall. To help avoid personal injury and vehicle damage, be sure to fit the jack lift head into the proper location before raising the vehicle.

  12. Remove any rust or dirt from the wheel bolts, mounting surfaces and spare wheel.
  13. Caution: Rust or dirt on a wheel or other parts to which it is fastened, can make the wheel nuts become loose and eventually the wheel could come off and cause a crash. Always remove all rust and dirt from wheels and other parts.

    Caution: Never use oil or grease on bolts or nuts because the nuts might come loose. The vehicle's wheel could fall off, causing a crash.

  14. Install the compact spare tire.

  15. Object Number: 810041  Size: A3

    Put the wheel nuts back on with the rounded end of the nuts toward the wheel. Tighten each nut by hand until the wheel is held against the hub.

  17. Object Number: 808642  Size: A2

    Tighten the wheel nuts firmly in a crisscross sequence as shown.

Caution: Incorrect or improperly tightened wheel nuts can cause the wheel to come loose and even come off. This could lead to a crash. If you have to replace them, be sure to get new original equipment wheel nuts. Stop somewhere as soon as you can and have the nuts tightened with a torque wrench to the proper torque specification. See Capacities and Specifications for wheel nut torque specification.

Notice: Improperly tightened wheel nuts can lead to brake pulsation and rotor damage. To avoid expensive brake repairs, evenly tighten the wheel nuts in the proper sequence and to the proper torque specification. See Capacities and Specifications for the wheel nut torque specification.

Do not try to put the wheel cover on the compact spare tire. It will not fit. Store the wheel cover in the trunk until you have the flat tire repaired or replaced.

Notice: Wheel covers will not fit on your vehicle's compact spare. If you try to put a wheel cover on the compact spare, the cover or the spare could be damaged.

Storing the Flat Tire and Tools

Caution: Storing a jack, a tire, or other equipment in the passenger compartment of the vehicle could cause injury. In a sudden stop or collision, loose equipment could strike someone. Store all these in the proper place.

After the compact spare tire has been installed on the vehicle, store the flat tire in the trunk. Use the following procedure to secure the flat tire in the trunk.


Object Number: 809502  Size: B3

When storing a full-size tire, use the extension with the protector, located in the foam holder, to help avoid wheel surface damage. To store a full-size tire, place the tire valve stem facing down, and then remove the protector and attach the retainer securely. Store the cover as far forward as possible.

Storing the Spare Tire and Tools

When storing a compact spare tire in the trunk, put the protector back in the foam holder.

Caution: Storing a jack, a tire, or other equipment in the passenger compartment of the vehicle could cause injury. In a sudden stop or collision, loose equipment could strike someone. Store all these in the proper place.

The compact spare is for temporary use only. Replace the compact spare tire with a full-size tire as soon as you can. See Compact Spare Tire . See the storage instructions label to return the compact spare to the trunk properly.
