TIRES SLIPPING ON WHEELS USE PROPER TIRE MOUNTING PROC

Subject: TIRES SLIPPING ON WHEELS (USE PROPER TIRE MOUNTING PROCEDURE) Models Affected: 1988-93 6000, SAFARI WAGON, FIREBIRD, BONNEVILLE, SUNBIRD, GRAND AM, GRAND PRIX AND TRANS SPORT MODELS

Some incidents of tires slipping (rotating) on wheels have been reported on 1988-93 passenger cars. Most incidents have occurred when driven aggressively immediately after tire mounting. Hard acceleration and/or braking is usually required. This condition will affect wheel balance, which could result in a vibration.

To reduce the chance of tires rotating on their wheels, any excess lube should be wiped from the tire and rim after tire mounting, but before inflating to seat the bead. (Never exceed 40 psi to seat the bead.) Also, the vehicle should not be driven aggressively for at least four hours after tire mounting to allow the lube to dry.

GM Goodwrench Rubber Lubricant, p/n 12345884, is the recommended lube for tire mounting.

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.
