What is the appropriate tire pressure?
2 Answers
Tire pressure should be inflated to 2.3 to 2.5 bar, according to relevant regulations and requirements: standard tire pressure is between 2.4 to 2.5 bar; reinforced tire pressure is between 2.8 to 2.9 bar; the maximum pressure should not exceed 3.5 bar. In winter, it is advisable to increase the standard tire pressure by 0.2 bar. In summer, when the car is parked outdoors, the pressure can generally be 0.1 bar lower than the standard to avoid tire blowouts due to high temperatures. When driving long distances on highways, the tire pressure should not be too low; it can be appropriately increased by 0.2 bar based on the lower limit of the standard tire pressure. When the tire pressure is too low, tire wear accelerates, increasing the risk of blowouts and fuel consumption. When the tire pressure is too high, tire grip decreases and wear accelerates, reducing braking performance.
I've been driving for over a decade and have deep experience with tire pressure. The standard value is usually found on the door label or in the owner's manual—my car recommends 30-35 PSI. Too low, and the tires wear out quickly while fuel consumption increases; I've even experienced a dangerous blowout on the highway due to underinflation. Too high, and the ride feels floaty with poor grip during turns, especially prone to skidding in rainy conditions. I make it a habit to check every two weeks, using a pressure gauge when the tires are cold—simple and safe. Seasonal changes have a big impact: in summer, heat causes expansion and higher pressure, so I release some air to around 32 PSI; in winter, I add a bit due to cold contraction. Don’t forget vehicle load—before a fully loaded trip, I inflate 2-3 PSI more to prevent deformation. Maintaining proper pressure long-term significantly extends tire life, saving money and ensuring peace of mind.
