A Package Deal! You get the Durometer and the Tread Depth Gauge - with foam lined carrying case.

The Durometer is a Racing Tire Hardness Tester. It's great for checking the condition of your tires. Tire hardness changes as tires get older and even varies between new tires. Now you can keep track of exactly where your tires are. Be precise, don't guess. It reads from 0-100 points.

The Tread Depth Gauge is exactly as it sounds. Again - Measure ... don't guess. This is super accurate, easy to read, easy to use. Calibrated in 1/32" and accurate to 1/128" (less than .010"!)
