What is the appropriate tire pressure for small cars in summer?

[DeEdward]

In summer, small cars generally require the lower limit of the standard tire pressure. For example, the lower limit for standard tires is 2.4 bar. If the car is often parked outdoors, the tire pressure can generally be about 0.1 bar lower than the standard to prevent tire blowouts due to high temperatures. Hazards of excessive tire pressure: The friction and adhesion of the tires will decrease, affecting braking performance; It can cause steering wheel vibration and deviation, reducing driving comfort; Accelerates localized wear of the tread pattern in the center of the tire, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Causes excessive stretching deformation of tire cords, reducing tire elasticity and increasing the load on the car during driving; Decreases puncture resistance. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, causing internal cracks and blowouts.
