What is the appropriate tire pressure in hot weather?

[ElizabethMarie]

Tire pressure in hot weather is appropriate between 2.3 to 2.5 bar. Tire pressure refers to the air pressure inside the tire. The hazards of excessive tire pressure are: 1. Increases the rigidity of the tire, reduces deformation and contact area; 2. Causes accelerated wear on the central part of the tire tread, shortening the tire's service life; 3. Makes the tire harder, leading to steering wheel vibration, deviation, and reduced ride comfort. Symptoms of low tire pressure include: 1. Steering wheel becomes heavy; 2. Car becomes unbalanced; 3. Reduced car speed; 4. Noise during driving. The functions of car tires are: 1. Work together with the car suspension to mitigate shocks encountered while driving; 2. Ensure good ride comfort and smooth driving; 3. Ensure good adhesion between the wheels and the road surface; 4. Improve the car's traction, braking, and off-road capability; 5. Bear the weight of the car.

As a driver who frequently takes long-distance trips, I pay special attention to tire pressure in hot weather because high temperatures cause air to expand, naturally increasing pressure and raising the risk of a blowout. It's recommended to refer to the label on the vehicle's door frame or the recommended values in the manual, usually between 2.2 and 2.5 bar. The key is to check the cold tire pressure in the morning before driving—adjust it to the standard value when the car hasn't been driven and the tires are cool. After driving in hot weather, the pressure may rise by a few tenths, but don't adjust it, as this can easily cause problems. Check it regularly once a week using a simple pressure gauge. Remember to check before hitting the highway—it saves fuel and ensures safety. Additionally, low tire pressure in hot weather increases fuel consumption and tire wear, while high pressure worsens handling. Many summer driving accidents are caused by this. Developing good habits extends tire life, and you can easily do it yourself.

As an experienced driver, I always check tire pressure in the scorching summer to avoid road accidents. The recommended tire pressure is usually labeled on the door frame, with most cars around 2.3 bar. In hot weather, the air expands, so measure it when the tires are cold before hitting the road—the pressure will naturally rise a bit, so don’t worry or overinflate. I usually check twice a month and adjust it with a home manual pump to maintain the recommended value, which saves fuel and reduces tire noise. Summer brings more rain, and incorrect pressure can also affect braking distance, so timely maintenance is crucial. By the way, check it at service stations before long trips—it’s simple and affordable. Overinflation risks tire bursts, while underinflation wears the sides, so make it a daily habit.

When I'm working, tire issues are common in hot weather, with air pressure problems ranking first. The key is to check cold tires, park in the shade, and set according to the vehicle's recommended value, usually around 2.4 bar. In summer, air expands quickly, and it's normal for the pressure to rise by 0.3 bar after driving—don't manually release air. It's recommended to use a simple pressure gauge monthly to ensure evenness. This maintenance is hassle-free and prevents accidents, as improper pressure in high temperatures can cause skidding or blowouts.
