What to Do When Car Tire Pressure Is Too High?
3 Answers
When the car tire pressure is too high, it is necessary to deflate the tires. Here is some relevant information about tire pressure: 1. Effects of excessive tire pressure: It increases the rigidity of the tire, reduces tire deformation and contact area with the ground, which can easily intensify wear in the central part of the tire tread and shorten the tire's service life; it makes the tire very hard, affecting ride comfort; it decreases the tire's resistance to punctures, making it more prone to blowouts when encountering sharp objects. 2. Causes of excessive tire pressure: Over-inflation leading to excessive tire pressure; inaccurate four-wheel alignment of the car, causing uneven tire wear and higher temperatures that increase tire pressure; excessive tire deflection, leading to higher wear temperatures and thus increased tire pressure.
High tire pressure is indeed not a good thing. It can cause the center of the tire to wear out quickly, reduce grip, and make the ride feel bumpy and unsafe. I once almost had an accident on the highway because of this. To solve the problem, first find a safe place to park, such as a parking lot or roadside, and use a tire pressure gauge to check the current pressure. Look at the sticker on the door frame for the recommended tire pressure value—usually, it's between 220 and 250 kPa for sedans. If the pressure is too high, use a deflation tool to slowly release some air, measuring again after each small release to avoid letting out too much at once. If you don't have the tools, just go to a repair shop and let them help—don't push through and keep driving. Also, consider whether recent temperature changes might have affected it. For example, tire pressure tends to rise in winter, so regular checks can prevent this. Safety first—don’t ignore it as a small issue.
As an average car owner, encountering high tire pressure is quite common. I usually first make sure the car is parked steadily, then take out the tire pressure gauge from the tire tool kit—these are inexpensive, just a few dozen bucks can get you a decent one. I measure the pressure of each tire, and if it's too high, say exceeding the manufacturer's recommended range, I carefully let out a bit of air. During this process, I repeatedly check with the tire pressure gauge to avoid overdoing it. I remember once during my novice days, I didn't do it properly and let out too much air, which resulted in the pressure being too low. Later, I learned the method of making small adjustments. High tire pressure not only affects comfort but can also accelerate tire aging and increase the risk of a blowout. So, it's best to develop the habit of checking once or twice a month, and you can also take the opportunity to check for any cracks or foreign objects stuck in the tires. Driving safety depends on the details—don't overlook these daily checks.
