To run your best you must keep track of all your tire's hardnesses. This easy-to-use tool will help you do just that - quickly, accurately & easily.
NEW Digital Readout 0-100 (Shore 'A' scale)
Longacre Digital Durometer w/Case Details:
For the most consistent results rock the durometer from angled back past straight up to angled forward. The readout will move up to the highest (true) reading, then back down. Record the highest reading reached. The durometer must have a straight edge on base to do this properly. If you just push straight down you may get inconsistent and inaccurate results.
