Longacre Basic Tire Durometer

The Longacre Basic Durometer measures changes in tire hardness so you can keep track of this important information. Using the Shore-A scale, the durometer reads from 0-100 points. A straight edge on the base of the durometer allows the user to rock the gauge for more consistant results. Non-slip coating on the back gives better grip for even more accurate readings. Includes hard plastic case.
