Tires/Wheels - Match Mounting Discontinued

Subject: TIRE/WHEEL MATCH MOUNTING DISCONTINUED

Models

Affected: 1991 ALL MODELS
Tire and wheel match-mounting has been eliminated on all 1991 models. 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.
