For 1990-2009 cars

# TEMPORARY USE SPARE TIRE APPLICATION AND USAGE

#### Models Affected: All

The purpose of this bulletin is to clarify General Motors' current usage of temporary spares on passenger cars (1983-84 models).

All GM cars are equipped with one of two types of temporary spares as standard equipment:

1. The stowaway (folding) spare is not used on any 1983-1984 Buicks.

2. The compact (high pressure) spare is the only spare used by Buick. It remains inflated and is designed to operate at 60 psi. This spare is usually smaller is diameter than the road tires, yet the wheel is usually one inch larger in diameter than the road wheels.

The compact spare is servicable using conventional equipment and procedures. The tire is available through Firestme, General, Goodyear, Goodrich and Uniroyal. The wheel is available through GM Parts. The wheels are compatible with compact spare tires only.

When properly inflated and installed, the (high pressure) spare will provide satisfactory service until the road tire can be conveniently replaced.

Tire size and pressure for the spare tire and road tires can be found on the tire placard located on the driver's door edge.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
