Should Tire Pressure Be Reduced in Summer?
2 Answers
Whether tire pressure needs to be reduced in summer depends on the current pressure. If the tire pressure of the car is between 2.3bar and 2.5bar, there is no need to reduce it. However, if the tire pressure exceeds 2.5bar, it is recommended to decrease the pressure by 0.1 to 0.2bar. Tires are the only part of the car that comes into contact with the ground, and they are crucial for the vehicle's driving stability and safety. Therefore, it is essential to pay attention to the condition of the tires. Tire pressure should neither be too high nor too low. If the pressure is too high, the contact area between the tire and the ground decreases, leading to reduced grip. Poor grip can negatively affect the car's handling and stability. On the other hand, if the tire pressure is too low, the tire may experience wave-like deformation during high-speed driving, which can shorten the tire's lifespan and increase the risk of a blowout.
I've been driving for over 20 years, and every summer people ask whether they should reduce tire pressure. I don't think it's necessary to do so. Hot weather naturally increases the air pressure inside tires. If you actively release air, the tire's support decreases and friction increases, which not only leads to excessive wear and damage but may also cause a blowout. I remember a friend who had an accident on the highway last year because of this. So, I'm used to checking tire pressure in the morning when the tires are still cool, setting it to the value recommended in the vehicle manual, such as around 30 psi written on the door frame. This can avoid problems, extend tire life, and save some fuel costs. I check it once a month with a tire pressure gauge, especially paying more attention before summer trips—safety first.
