Tread Depth Gauges
An accurate tread depth gauge can detect developing wear patterns earlier than simply looking at the tread. This often allows the cause to be identified and corrected before excessive or irregular tread wear ruins the tire. DiscoveryParts' gauges are super accurate, easy to read, and easy to use. All come with a pouch and/or silver carrying case.
