Corp. Ref. No.: 873504
SUBJECT:
TIRE/WHEEL MOUNTING
MODELS AFFECTED: 1989 CENTURYS, REGALS, ELECTRAS AND PARK AVENUES, LESABRES, RIVIERAS AND REATTAS
Continuous improvement in the manufacturing process of both steel and aluminum wheels has resulted in greatly reduced variations. Additional tire
variation reductions have also been achieved. Because of this, match mounting of tires and wheels at the assembly plant is no longer necessary on some
models. For 1989, the following carlines will be random mounted (not match mounted):
Century, Regal, Electra/Park Avenue LeSabre, Riviera and Reatta
Some tire manufacturers will continue to identify the high point of the tire with a painted dot or adhesive sticker so that match mounting can still be
accomplished on other car lines.
Dealers should not dismount the tire to align the wheel's valve with the tire's high point mark, since this will not improve the ride or handling
characteristics of these vehicles.
