By Monitoring your tyres when out on a track day or when racing is one of the most effective things you can do to make your car as grippy and as fast as possible with minimal effort. Your tyres are the final point of contact between your car and the ground. Therefore, they transmit a lot of information from your suspension set up and also store a lot of useful information that can be measured to help fine tune your geometry to make the tyre work more efficiently with the ground to make your car go faster with ease.
