Should Car Tires Be Deflated in Summer?
2 Answers
If the cold tire pressure is higher than the manufacturer's recommended standard tire pressure, then deflation is necessary; if the cold tire pressure is still below the standard tire pressure, do not consider deflation but rather add some air. The general principle is to maintain the manufacturer's recommended standard tire pressure, without deliberately increasing or decreasing it, as both overinflation and underinflation can have negative effects on the tires. Specific information is as follows: 1. Manufacturer's regulations: Under normal driving conditions, even in hot summer, simply inflate the tires according to the manufacturer's specifications, and there is no need to reduce the tire pressure on your own. 2. Cold and hot tire pressure: Cold tire pressure refers to the tire pressure when the car has not been driven. Hot tire pressure refers to the tire pressure after the car has been driven for a long distance.
In summer, should I let air out of my car tires? That's a good question. As someone who frequently works on cars, I don't recommend intentionally deflating them. Rising temperatures do increase tire pressure, usually by about 5-10%, but if you actively lower it, the tires are more prone to deformation, accelerated wear, and increased risk of blowouts. The key is to check the cold tire pressure: find a morning or when the car has cooled down, use a tire pressure gauge to measure the PSI number recommended on the door placard, and keep it within the normal range. For example, my SUV recommends 35 PSI; if it reads 40 when the car is hot in summer, don't panic—just adjust it back to the standard when it's cold next time. Regular checks are better than random adjustments; I check mine every two weeks, paying extra attention to weather changes in summer. This saves fuel and ensures safety, making the car much more stable to drive.
