Tread Wear

As your tires wear down, their ability to grip the road decreases. Each tire has what are known as wear bars. These appear at various points around the tire as bars running through the tread design from one side of the tire to the other. When your tires are legally worn out (2/32") the tread will be at the same level as the tread wear indicators and they will be easily visible. Usually before the tire gets to this point, they will begin to feel unsafe. If that is the case, do not wait for them to get to the wear bars. Just because the tread depth is not as low as the tread wear bar, does not mean it is safe.
