What is the general tire pressure in summer?
2 Answers
In summer, a tire pressure of 2.3 bar is most suitable. Due to the high temperatures in summer, the tire pressure should be 0.1-0.2 bar lower than the standard tire pressure recommended by the car manufacturer. Below is additional information on the effects of excessive tire pressure: 1. Excessive tire pressure reduces the adhesion between the tire and the ground, leading to decreased braking performance and a shortened tire lifespan. 2. Excessive tire pressure makes the tire abnormally fragile, significantly reducing its resistance to punctures. Sharp objects like glass or nails can easily penetrate the tire, causing a blowout. 3. Excessive tire pressure accelerates localized wear on the central tread pattern, causing the car to vibrate and potentially affecting the lifespan of other components over time. Below is additional information on the effects of insufficient tire pressure: 1. Insufficient tire pressure causes the tire to flatten, increasing the friction area with the ground, which leads to higher fuel consumption. It also makes the steering wheel heavier and increases the likelihood of the car pulling to one side. 2. Insufficient tire pressure generates excessive heat during driving, reducing the functionality of the tire cords and rubber, resulting in damage and abnormal wear at the bead area. 3. Insufficient tire pressure prevents the tire from reaching its standard strength. Due to increased friction with the ground, the tire is more prone to blowouts during high-speed driving.
There's actually no fixed standard for summer tire pressure. Check the manufacturer's recommendation on the door frame or fuel filler cap, usually between 2.2 to 2.5 bar when cold. We often discuss this in our car owners' group - summer roads get hot enough to fry eggs, causing tire pressure to rise by about 0.2. If you inflate to winter pressure, it might reach 3.0 on highways, making tires hot to touch and increasing braking distance. I check monthly with a mechanical gauge (most accurate before morning drives), releasing some air if over 2.7. My neighbor wore out treads quickly - turned out he kept 3.0 pressure year-round. Don't forget spare tires either, they're prone to aging/leaks in summer.
