Durometer Gauge, 0-100 Points, Mechanical, Analog

Intercomp's tire durometers enable you to make the correct tire selections for any track. The surface of a tire becomes harder with every heat cycle, and even new tires of the same compound can vary a great deal in hardness. If a tire is too soft for the track, it will overheat and may not last the entire race. If it is too hard, it will not get up to the optimum temperature, and traction will have to be sacrificed.
