What is the appropriate tire pressure for summer tires?
2 Answers
The appropriate tire pressure for summer tires is between 2.3 and 2.5 bar. Seasonally speaking, the standard and recommended data given by the industry are 2.3 bar for the front tires and 2.5 bar for the rear tires in summer; in winter, it is 2.5 bar for the front tires and 2.7 bar for the rear tires. Depending on the vehicle model and style, the tire pressure data may vary slightly, but the difference will not be significant. If the tire pressure is insufficient, tire deformation will increase, the tread on both sides of the tire will wear excessively, and the tire body will twist and deform due to its inability to withstand ground pressure, generating high temperatures that accelerate tire wear and lead to blowouts. Excessive tire pressure will make the tire too hard, losing elasticity and shock absorption capacity, resulting in poor grip. Excessive wear on the central tread will cause uneven tread depth, and the tire may also blow out due to its inability to withstand excessive pressure during high-speed operation.
Maintaining proper tire pressure in summer is crucial. Based on my years of driving experience, the general standard is to check the label on your car door or the user manual, with a recommended range between 32 to 35 PSI (pounds per square inch). In summer, high temperatures cause air to expand and pressure to rise. If the pressure is too high, it can lead to rapid wear in the center of the tire and increase the risk of a blowout at high speeds. If it's too low, the edges will wear out quickly, fuel consumption will soar, and handling will be poor. I recommend measuring the pressure when the car is cold in the morning for the most accurate reading, as the error is larger when the car is hot. Check every two weeks, and always do so before long trips. Don’t forget the spare tire—set it to a moderate level to ensure safety and comfort, and to extend tire life. By the way, gas stations often have free air pumps, and regular maintenance can also save you money on fuel.
