How normal is the tire pressure in summer?

In summer, the tire pressure is generally between 2.0 bar and 2.2 bar.

Please refer to the owner's manual for the specific tire pressure of each vehicle. You can see the recommended value of the manufacturer above. According to the provisions and requirements of international GBT2978-2008 standard: standard tire: 2.4 bar -2.5 bar; Enhanced wheels: 2.8 bar -2.9 bar; Maximum atmospheric pressure: not more than 3.0 bar.

If the tire pressure is lower than 2.0bar, it needs to be replenished in time. Too high tire pressure will make the tire hard, and too low tire pressure will lead to reduced handling and accelerated tire wear. Note that the overall tire pressure in summer is about 10% lower than in other seasons. In other words, the safest tire pressure range in summer should be between 2.0 bar and 2.2 bar. Tire pressure, strictly speaking, refers to the pressure of air inside the tire. The engine is the heart of the car in car maintenance, and the damage of the engine will lead to the exhaustion of the life of the car, so 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.
