What should the car tire pressure be in summer?
2 Answers
In summer, the car tire pressure should be maintained at around 2.3 to 2.5 bar. Tire pressure refers to the air pressure inside the tire, and the methods to check it include: 1. Measuring with an instrument; 2. Visual inspection method; 3. Consulting the staff at a 4S shop. The relationship between tire pressure and car performance: 1. Tire pressure is an indicator of the car's load capacity—the higher the pressure, the greater the load capacity; 2. Tire pressure has a significant impact on the rolling resistance coefficient—when the pressure decreases, the rolling resistance coefficient increases rapidly; 3. The inflatable method for tires improves ride comfort; 4. Appropriately reducing tire pressure can increase tire deformation, enlarge the contact area with the ground, enhance adhesion, and ensure good braking performance of the car.
As someone who drives frequently, I find summer tire pressure crucial. My car is a regular sedan, and the label on the door recommends 32 PSI. However, on hot summer days, high temperatures cause the air in the tires to expand, and the actual pressure while driving can rise above 35, which is dangerous and increases the risk of blowouts or skidding. So, I usually check the cold tire pressure in the cool morning hours and keep it between 29 and 31 for safety. Regular checks are also essential—every two weeks or before long trips—because I've noticed that overly low tire pressure causes issues too: fuel consumption increases by about 10%, tires wear out faster, and their lifespan shortens. After replacing tires a few times, I've become more attentive to this small detail—safety comes first, after all. Proper tire pressure saves on repair costs and ensures smoother highway driving. By the way, keeping a portable tire pressure gauge in the car is very convenient, eliminating the need to visit a shop.
