Race Car Tire Pressure. See all hoosier racing tires. Hydroplaning occurs when a wedge of water develops between the tire and road surface.
Tire pressure can be 3 to 5 psi higher when scuffing but must be reset before the race begins. We would expect a hot tyre pressure in this range just like your much heavier production car requires a hot tyre pressure about 35psi. See all hoosier racing tires.
There are other ways to make large changes to the cross weight of my car.
Tire manufacturers will recommend a specific pressure such as 32 psi so instead of doing all the temps to adjust the pressures you just adjust the tires to the recommended pressure. This wedge can actually lift the tire off the road and eliminate traction. Tire pressure in the rain for both autocross and road racing increase tire pressures 6 8 psi from what you would normally run in dry conditions. Tire pressure will rise about 5 10 psi when the tires heat up depending on the tire itself track friction and driver skill level.
