How much is the tire pressure suitable for cars in summer?

Automobile tire pressure, strictly speaking, refers to the pressure of air inside the tire. If the engine is the heart of the car, the damage of the engine will lead to the exhaustion of the life of the car, then the tire pressure is the blood pressure of the car, and the level of tire pressure plays a vital role in the performance and power of the car. So, how much is the tire pressure of the car suitable in summer? This article will briefly share this knowledge:

In the case of high temperature in summer, the value between 2.4 and 2.5 bar is the most normal. There is no need to deliberately reduce the tire pressure. As for the problem that high temperature will make the gas inside the tire expand with heat and contract with cold, the manufacturer has already considered it when designing, so the given normal tire pressure is also suitable for high temperature weather in summer, even if driving at high speed.

If the tire pressure is too high, if it is much higher than the standard tire pressure, the friction and adhesion of the tire will be reduced, which will affect the braking effect, lead to steering wheel vibration and deviation, and reduce driving comfort. At the same time, it accelerates the local wear of the central tread pattern of the tire, reduces the service life of the tire, increases the vibration of the car body, and indirectly affects the service life of other parts. Excessive tire pressure will also cause excessive tensile deformation of tire cord, decrease the elasticity of carcass, increase the load when the car is running and reduce the rolling resistance. When encountering sharp objects such as nails and glass on the road, it is easy to plunge into the tire, and the tire is impacted to produce internal cracks and explosions, resulting in a puncture.

If the tire pressure is too small and too much lower than the standard tire pressure, the friction coefficient between the tire and the road surface will increase, the fuel consumption will increase, and the steering wheel will be heavy and prone to deviation. If the tire pressure is insufficient, the amount of exercise in all parts of the tire will increase, and excessive rolling will cause abnormal heating of the tire, which will reduce the functions of the cord and rubber, cause cord breakage and delamination or excessive friction between the rims, and lead to damage and abnormal wear of the beads. The friction between the tire and the ground will increase exponentially, which will also lead to a sharp rise in tire temperature, tire softening, and a sharp decline in strength. When the vehicle runs at high speed, it will also lead to a flat tire.
