What is the normal tire pressure for cars in summer?
2 Answers
In summer, the normal tire pressure for cars is between 2.2bar and 2.4bar. As the temperature and road surface temperature rise, the tire pressure can easily increase during high-speed or long-distance driving. Excessive tire pressure reduces the contact area between the tire and the ground, leading to a significant increase in pressure and wear per unit area, which can easily cause brake failure and damage the vehicle's suspension system. Summer car tire maintenance tips: 1. Inspect the vehicle tires to check for stones or foreign objects in the tire grooves, and examine the tire sidewalls for scratches or punctures that may expose the cords; 2. Check the tire pressure to ensure it is within the standard range, neither too high nor too low; 3. For vehicles frequently driven long distances or at high speeds, it is necessary to rotate the tires regularly.
I've been driving sedans for over a decade, and summer tire pressure management is not to be taken lightly. The standard tire pressure for sedans is usually marked on the door frame or in the glove compartment manual, typically between 32 to 35 PSI. Hot weather causes tires to heat up and expand, increasing tire pressure by 2 to 3 PSI, so it's best to set the cold tire pressure a bit lower—I recommend between 28 to 31 PSI for a balance of safety and efficiency. The safest approach is to measure and inflate tires with a pressure gauge in the cool morning, as high temperatures can cause tire deformation and increase the risk of blowouts, especially when driving at high speeds. Long-term maintenance can save fuel and extend tire life. I've developed a habit of weekly morning checks and bought an inexpensive portable tire pressure gauge. Don’t forget to adjust promptly if tires wear unevenly, otherwise, poor handling and increased chances of skidding in rainy conditions can lead to accidents.
