Is a tire pressure of 2.2 bar normal in summer?
2 Answers
A tire pressure of 2.2 in summer is not low, maintaining tire pressure at 2.2 during summer is within the normal range. Hazards of low tire pressure: Increased fuel consumption: Low tire pressure increases the contact area between the tire and the ground, thereby increasing tire friction, leading to greater driving resistance and naturally higher fuel consumption. Shortened tire lifespan: Similarly, due to the increased contact area with the ground, tire wear is accelerated, reducing the tire's service life. Increased risk of blowouts: The increased friction causes the tire temperature to rise, making the tire softer and reducing its strength. When the tire can no longer support the vehicle's load, especially during high-speed driving, it is more prone to blowouts.
I'm a guy who's been driving for decades and know a thing or two about tires. Summer tire pressure at 2.2 bar? Sounds a bit low. Normally, car tire pressure should be between 2.2 and 2.5 bar, but when it's hot, tire expansion can easily exceed safety limits. I recommend maintaining 2.3 or 2.4 bar when cold to reduce wear and fuel consumption. Once I didn't pay attention and went on a long trip in hot weather - the tire pressure soared to 2.7 bar and I almost had a blowout. For safety's sake, check with a pressure gauge before each trip or refer to the recommended values on the door frame. Different tire types also matter - performance tires might require slightly higher pressure. Bottom line, don't ignore this - prevention is better than cure.
