Tire Pressure is Controlled and Set by Tire Temperature. Period. Any good chassis engineer will tell you that. If last year's tire budget was $1800 but you didn't get the full contact patch from your race alignment, then that hard earned money was not well spent.
A good pyrometer will make sure you get the correct contact patch from the inside of your tire to the outside of your tire. How do you control the temperature across a tire? By adjusting tire pressure. A tire that is over inflated will ride only in the center and an under inflated tire will cup in the center. We run a certain amount of camber in a car to assist in laying the tire flat in a loaded corner, but the final contact is dictated by the pressure of the tire making the tire contact shape.
DiscoveryParts offers a great selection of tire pyrometers to help you not only corner faster but save some of that tire budget.
