Racing Tire Hardness Tester

Tire hardness has a huge affect on your car's performance. A tire too hard won't bite and a tire too soft may wear quickly or even ball up. Also tire hardness changes during its life cycle. 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)

  • Straight edge on base to 'rock' durometer for more consistant results
  • Non-slip coating for better grip
  • Calibration test block included
  • Accurate easy-to-use
  • Includes Silver case and pouch
  • Reads in .5 increments

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.

This is a quality gauge - I had a cheaper (China) one and the results were just too inconsistent to be of any use.
