What is the standard tire pressure for cars in summer?
2 Answers
In summer, the tire pressure for cars can generally be set to the lower limit of the standard tire pressure. For example, the lower limit for standard tires is 2.4 bar. If the car is often parked outdoors, the tire pressure can be about 0.1 bar lower than the standard to prevent tire blowouts due to high temperatures. Hazards of excessive tire pressure: The friction and adhesion of the tires will decrease, affecting braking performance; It can cause steering wheel vibration and deviation, reducing driving comfort; Accelerates localized wear of the tread pattern in the center of the tire, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overextends the tire cords, reducing tire elasticity and increasing the load on the car while driving; Decreases puncture resistance. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, causing internal cracks or blowouts due to impact.
When it comes to standard tire pressure in summer, I think from years of driving experience, it's actually quite simple. The standard tire pressure is usually indicated on the sticker inside your car door frame or in the owner's manual, typically between 2.2 and 2.5 bar. In hot summer weather, air tends to expand, causing tire pressure to increase by 0.2 to 0.3 bar, so regular checks are necessary. When I drive my SUV in summer, I always maintain a cold tire pressure around 220 kPa to avoid the risk of blowouts due to overheating tires during high-speed driving. If the tire pressure is too low, handling becomes poor, making it difficult to control in emergencies; if it's too high, tire wear accelerates and fuel consumption increases. I recommend buying a tire pressure gauge and checking it every week or two when the car is cold in the morning. If you drive long distances frequently in summer, tire pressure changes significantly, so don't forget to adjust it promptly.
