Tires: Testing and Inspection
Tire and Wheel Inspection
Tire and Wheel Inspection
The tires on all new production models have a tire performance criteria (TPC) rating number molded on the sidewall. The TPC rating will appear as a
4-digit number preceded by the letters TPC SPEC on the tire wall near the tire size. A replacement tire should have the same TPC rating.
Inspect the tire and wheel assemblies for the following conditions:
^
Unusual wear such as cupping, flat spots, and/or heel-and-toe wear
These conditions can cause tire growl, tire howl, slapping noises, and/or vibrations throughout the vehicle.
^
Proper inflation to specifications for the vehicle
^
Bulges in the sidewalls
Do not confuse bulges, which are an abnormal condition, with normal ply splices which are commonly seen as indentations in the sidewall.
^
Bent rim flanges
