Tires - Slipping on Wheels

Bulletin: 93-3-6

Date: April '93

Ref.No.: 93-133-3

Corp.Ref.No.: 393501

SUBJECT:
TIRES SLIPPING ON WHEELS
(USE PROPER TIRE MOUNTING PROCEDURE)

MODELS AFFECTED:
1988-93 BUICKS

Some incidents of tires slipping (rotating) on wheels have been reported on 1988-93 Buicks. 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.
