 If you sell or service tires, then you know the importance of having  enough tread for safe driving.

The measurements are separated into three colors: green,  yellow, and red. The green range is 6/32+, the yellow range is 3/32 -  6/32, and the red range is 0-3/32. This gauge also reads in both MM and  32nds for added convenience.
