What is the pressure range for car tires?
2 Answers
The pressure range for car tires is between 2.3bar and 2.5bar. Since tires are made of rubber material, following the principle of thermal expansion and contraction, the tire pressure in summer can be 0.1bar to 0.2bar lower than the normal value, while in winter it can be 0.1bar to 0.2bar higher than the normal value. Car owners should replenish the tire pressure according to the specified range for their vehicle model. Too low tire pressure will increase tire wear, while too high pressure will affect comfort. Tire pressure refers to the air pressure inside the tire. In car maintenance, the engine is the heart of the car, and engine damage will lead to the end of the car's life. The tire pressure is the blood pressure of the car, and the level of tire pressure plays a crucial role in the car's performance and power.
Having driven for over twenty years, I can't stress enough the importance of tire pressure. The general range is around 30 to 35 psi, but the exact value depends on your vehicle model and tire size, which can be found on the label inside the door or in the user manual. Too low is no good—it accelerates tread wear, increases rolling resistance, and can lead to longer braking distances, raising the risk of accidents. Too high, and the excessive pressure reduces grip, making cornering unstable. I recommend checking it once a month, preferably on a clear morning using a reliable tire pressure gauge to measure cold tire pressure. Remember, seasons have a big impact—tire pressure rises in summer due to higher temperatures, while in winter, you may need to adjust it slightly higher. A digital tire pressure gauge costs just a few bucks and is a handy tool to keep in your car for peace of mind. Safe travel is what really matters.
