Tires/Wheels - Match Mounting Discontinued

Number: 91-80-3E

Section: 3E

Date:: October 1990

Corp. Bulletin No.: 093501
Subject: TIRE/WHEEL MATCH MOUNTING DISCONTINUED


Model and Year: 1991 PASSENGER CARS AND TRUCKS
TO: ALL CHEVROLET DEALERS


Tire and wheel match-mounting has been eliminated on all 1991 GM cars and trucks. This is possible because tires and wheels are now manufactured to very close tolerances, which essentially eliminates any "high" or "low" points.

A high point label or dot may still be on some tires, but it will not necessarily line up with the wheel's valve. Dealers should NOT dismount the tire to align this mark with the valve, as no improvement in tire/wheel match will occur.
