Having sufficient tread on tires is important for safe driving. Make checking treads fast and effortless with the Steelman Color-Coded Tread Depth Gauge. Easily identify how much tread depth is left on each tire with the red, yellow, and green color tiers. The green range is 6/32+ (4.75mm), the yellow range is 3/32-6/32 (2.4-4.75mm), and the red range is 0-3/32 (0-2.4mm). For added convenience, one side of the gauge reads in mm and the other in 32nds of an inch. The gauge is designed to hold the measurements for easy reading rather than immediately springing back into a neutral position. Featuring a pin clip, this compact gauge easily secures inside a pocket when not in use.
