How much does tire pressure increase when driving on the highway?

[LilaRose]

Tire pressure increases by 0.4 to 0.6 bar when driving on the highway. The normal tire pressure temperature is between 2.2 and 2.4 bar, and tire pressure rises as the temperature increases. During high-speed driving, especially during emergency braking and rapid acceleration, tire temperature rises quickly. For every 10-degree increase in tire pressure temperature, the pressure increases by 0.1 bar. Therefore, maintaining tire pressure at the standard value helps avoid blowouts during high-speed driving and emergency braking. During long-distance driving, the tires generate heat from prolonged friction, and tire pressure increases in high-temperature environments. It is not advisable to lower tire pressure excessively to prevent blowouts, as excessively low tire pressure can also lead to blowouts. Low tire pressure increases the contact area between the tire and the ground, putting more pressure on the tire shoulders, which generates heat through internal friction, consumes the gas inside the tire, and damages its internal structure.
