LONGACRE DIGITAL HARDNESS TEST

Racing Tyre Hardness Tester. The hardness of your tyres has a huge effect on your car's performance. A tyre that is too hard will not bite and a tyre that is too soft can wear out quickly or even form a ball. Also the hardness of the tyre changes during its life cycle. To run at its best, you need to keep track of all of your tyres' hardnesses. This easy-to-use tool will help you do just that - quickly, accurately and easily.
