Tires - Slipping on Rim
BULLETIN NUMBER: 93-3E-63
SECTION: 3E
NUMBER: 2
CORPORATE REFERENCE NUMBER: 393501
DATE: April 1993
SUBJECT:
TIRES SUPPING ON WHEELS (USE PROPER TIRE MOUNTING PROCEDURE)
MODELS:
1988-93 LIGHT DUTY TRUCKS
Some incidents of tires slipping (rotating) on wheels have been reported on 1988-93 light duty trucks. 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.
