Longacre Durometer with Case
Racing Tire Hardness Tester
Tire hardness has a huge affect on your kart'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.
- Reads from 0-100 points
- Comes with silver case
For the most consistent results rock the durometer from angled back past straight up to angled forward. The pointer will move up to the highest (true) reading, then back down. Record the highest reading reached. The durometer must have a rectangular base to do this properly. If you just push straight down you may get inconsistent and inaccurate results.
