What is the appropriate tire pressure for car tires in hot weather?
2 Answers
The appropriate tire pressure for car tires in hot weather is between 2.3bar and 2.4bar, but the specific value should be determined based on the manufacturer's recommendation. Due to the principle of thermal expansion and contraction, the tire pressure in hot weather should be maintained at the lower limit of the standard tire pressure. If the car is parked under the sun in hot weather, the tire pressure should be reduced by 0.1bar from the standard tire pressure to avoid tire blowouts caused by high temperatures. Tire pressure refers to the air pressure inside the tire, which is the 'blood pressure' of the car. The level of tire pressure plays a crucial role in the car's performance and power. Tire pressure is an indicator of the car's load capacity. The size of the car's load depends on the level of tire pressure. According to the relationship between the tire's load index, tire pressure, and load capacity, the higher the tire pressure, the greater the load capacity, and the lower the pressure, the smaller the load capacity.
Tire pressure is crucial when driving in hot weather. Having driven for over a decade, I'm most wary of tire issues in summer. I remember one scorching day when I took my family on a trip—the tire pressure was too high, causing a bulge that nearly led to an accident. Since then, I've learned my lesson: always maintain the recommended tire pressure for your vehicle, usually found on the door frame label or manual, such as 35 to 40 psi. Never adjust it arbitrarily. Hot weather causes the air inside tires to expand, increasing pressure and the risk of a blowout, while too-low pressure increases friction and fuel consumption. I recommend checking tire pressure in the early morning when the car is still cool for the most accurate reading, and keeping a tire pressure gauge handy for regular checks. During prolonged hot weather, checking weekly is advisable, and always inspect carefully before long trips. This not only protects your tires and extends their lifespan but also saves fuel and ensures safety.
