"How Temperature Affects NASCAR Tire Pressure and Performance"
Temperature plays a critical role in NASCAR tire performance, directly affecting tire pressure and, consequently, a car's handling and speed. As temperatures rise on a hot race day, the air inside the tire expands, increasing pressure by roughly 1-2 psi for every 10°F increase. This higher pressure reduces the tire’s contact patch with the track, potentially decreasing grip but boosting top speed due to lower rolling resistance. Conversely, cooler temperatures lower tire pressure, increasing grip but risking sluggish handling if pressures drop too low. NASCAR teams meticulously monitor and adjust tire pressures to optimize performance, ensuring drivers maintain control and competitiveness under varying track conditions.
I do this for free, but if you'd like to tip, here are some ways to do so. Any tips help keep this going, and I greatly appreciate all the support!
