What are the effects of high tire pressure in cars?

[AugustLynn]

The friction and adhesion of tires will decrease, affecting braking performance; it will cause steering wheel vibration and deviation, reducing driving comfort; accelerate localized wear of the tread pattern in the central part of the tire, affecting tire lifespan; increase vehicle body vibration, indirectly impacting the lifespan of other components; it will cause excessive stretching deformation of tire cords, reducing tire elasticity, and increasing the load on the car during driving. According to the provisions and requirements of the international GBT2978-2008 standard, the tire pressures for different tires are as follows: Standard tires: 2.4-2.5bar; reinforced tires: 2.8-2.9bar; the maximum pressure should not exceed 3.5bar. Normal tire pressure in winter: In winter, tire pressure should be based on the standard tire pressure of the car, with an appropriate increase of about 0.2bar. Normal tire pressure in summer: Generally, the lower limit of the standard tire pressure for car tires is sufficient. For example, the lower limit for standard tires is 2.4bar. If the car is often parked outdoors, the tire pressure can generally be about 0.1bar lower than the standard to avoid tire blowouts due to high temperatures.
