Removing the Flat Tire and Installing the Spare Tire
On the professional vehicle, each wheel has eight wheel nuts.
Tighten the wheel nuts firmly in a criss-cross sequence as shown.
Caution: Incorrect wheel nuts or improperly tightened wheel nuts can cause the wheel to become loose and even come off. This could lead to an accident. Be sure to use the correct wheel nuts. If you have to replace them, be sure to get new GM original equipment wheel nuts. Stop somewhere as soon as you can and have the nuts tightened with a torque wrench to 100 lb-ft (140 N·m).
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.

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:
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.
When the vehicle has a flat tire (B), use the following example as a guide to assist you in the placement of wheel blocks (A).
