Tread Wear Indicators

Tread wear indicators molded into modern tires serve as visual proof that the tire tread is approaching worn-out condition. These 1/2 inch indicators are located in several positions around the circumference of the tire. As long as the tread grooves are at least 1/16 deep, the grooves are unbroken. When tread depth reaches that point, the tread wear indicators will appear as solid strips across the tire. These strips interrupt tread continuity and are clearly visible upon inspection. The tire should be replaced when this occurs.
