How Does Tire Pressure Change When Tires Get Warm?
Tire pressure changes when tires get warm due to the increase in temperature of the air inside the tire. Warmer air expands, which raises the pressure in the tire. When a vehicle is driven, friction from the road generates heat. This heat elevates the temperature of the tire and the air within it.
As temperature increases, the molecules in the air move more vigorously, leading to an increase in pressure. For every 10°F rise in temperature, tire pressure can increase by approximately 1 psi (pound per square inch). This means that if a driver’s tire is set to the recommended pressure when cold, it will register a higher pressure after driving because of the heat produced.
To ensure optimal performance and safety, drivers should check tire pressure when the tires are cold. This approach accounts for the natural increase in pressure due to heat and helps maintain proper inflation levels. Understanding this relationship between temperature and tire pressure is essential for effective vehicle maintenance.
