Tires have small wear bars molded into the tread grooves. When the tread is worn down to the level of the wear bars (indicating 1/32 inches of tread remaining), the wear bars become exposed and the tire should be replaced. Some manufacturers recommend replac-ing the tire when there are 2/32 or 3/32 inches of tread remaining. Al
