Wear Indicator
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
