Is it dangerous to drive at a high speed with a tire temperature of 55 degrees?

When the temperature is higher than 30℃, the air pressure in the tire will increase from 10% to 12%, and the tire is easy to bulge. If the tire itself is scratched, there is a great possibility of puncture, and the road temperature may reach 60~70℃ in summer. If the tire pressure is too high, it is easy to puncture when it touches the weak part of the tire.

Therefore, cars that often run at high speed mainly develop the habit of regularly checking tire pressure. Also note that after driving in hot weather, don't rush to wash the tires. Due to the high contact temperature between the tire and the ground for a long time, the tire wall is easily deformed or uneven when it is suddenly impacted by cold water, and the tire wall will also be wrapped around the cold shrinkage tire wall, resulting in a puncture. The tire pressure can be reduced by 10%, and the tire can also be filled with nitrogen to ensure safety.

Extended data

Driving time should not be too long in hot weather. Stop and rest properly every 2 hours or after driving a certain distance, and check whether the tire temperature and tire pressure are too high. When it is found that the tire is overheated and the tire pressure rises, you should park your car in a cool place or a cool place to let the tire cool down and depressurize naturally. It is not allowed to deflate or pour cold water to avoid accidents such as puncture.

In addition, driving in hot weather is very easy to make people sleepy. Owners should not drive tired or rest in the car with the air conditioner on. Under the exposure of the sun, the highest temperature in the car can reach above 80 degrees Celsius, and lighters and perfumes in the car are easy to explode or burn. Therefore, flammable and explosive articles such as lighters and perfumes cannot be placed in the car, especially under the windshield of direct sunlight.
