Why Does Tire Pressure Increase While Driving?

[VonEmersyn]

Tire pressure increases while driving due to the expansion of gas inside the tires. Below is an extended explanation about tire pressure: 1. Vehicle model affects tire pressure: Generally, the normal tire pressure should follow the manufacturer's recommended value. The standard tire pressure is related to the type of tire, and different vehicle models have varying weights, heights, and tire sizes, thus requiring different tire pressures. Standard tires typically have a pressure of 240kpa-250kpa, while reinforced tires have a pressure of 280kpa-290kpa. 2. Temperature also has an impact: The tire pressure differs between cold and hot tires, with hot tires having about 20kpa higher pressure than cold tires. The manufacturer's recommended value refers to the cold tire pressure, which is usually around 230kpa-250kpa when the vehicle is stationary, but the exact value should be based on the specific tire pressure indicated for each vehicle.
