Tread Wear Indicators

DIAGNOSIS AND TESTING - TREAD WEAR INDICATORS

Fig. 2:

Tread wear indicators are molded into the bottom of the tread grooves. When tread depth is 1.6 mm (1/16 inch), the tread wear indicators will appear as a 13 mm (1/2 inch) band.

Tire replacement is necessary when indicators appear in two or more grooves or if localized balding occurs.
