What is the normal tire pressure for cars in summer?
2 Answers
For cars in summer, the normal tire pressure ranges between 2.1bar and 2.4bar. Generally, the tire pressure for car tires is between 2.2bar and 2.5bar, and it is safe as long as it falls within this range. However, due to high temperatures in summer, the tire pressure may actually rise to above 3.0bar. Car owners should frequently check whether the tire pressure is within the standard range—it should not be too high or too low, as both extremes can easily lead to tire blowouts. Excessive tire pressure reduces resistance to punctures, making it easier for sharp objects like nails or glass on the road to penetrate the tire, and the impact can cause internal cracks and explosions, resulting in a blowout.
The normal tire pressure for summer car tires is between 2.3 and 2.5 bar. Refer to the vehicle manual or the label on the door frame. My experience is to check the cold tire pressure before driving out on hot days, as tire pressure tends to rise with higher temperatures. Too high pressure can cause a blowout, while too low pressure increases fuel consumption. It is recommended to adjust it to 2.2 or 2.3, slightly lower than usual, and check it weekly using a pressure gauge or by getting it measured for free at a gas station. Check more frequently on long trips to ensure a smooth and safe ride.
