* Temperature: As the tire rolls along the road, it generates heat due to friction with the road surface. This heat causes the air inside the tire to expand, increasing the pressure.
* Tire flexing: As the tire rotates, it flexes slightly due to the weight of the car and the bumps in the road. This flexing also causes the air inside the tire to be compressed and heated, leading to an increase in pressure.
* Centrifugal force: As the tire spins, the air inside it experiences centrifugal force, which pushes the air towards the outer edge of the tire. This can cause a slight increase in pressure, especially at high speeds.
It is important to note that the increase in air pressure during driving is typically small and within the recommended limits for the tire. However, it is still important to maintain proper tire pressure according to the manufacturer's specifications to ensure optimal performance and safety.
