How high can a car tire be?

Different grades of tires have different high temperature resistance. Generally speaking, the highest temperature that automobile tires can withstand is 180-200 degrees Celsius. Usually, the temperature of A-class tires with a speed of 120km/h is close to 100 degrees Celsius. When braking, the tire temperature is close to 200 degrees Celsius.

In general, the running temperature of the tire is between 90- 1 10 degrees Celsius, and the tire has a heat insulation sleeve, which can generally keep the temperature within the controllable range. Hot weather can easily lead to tire deformation, reduced tensile strength, nonstandard tire pressure, or tire aging and performance weakening, leading to tire puncture. Too high tire temperature is very dangerous, because the tire is in contact with the high-temperature road for a long time, and the heat accumulation is intensified, which leads to the rapid decline of the mechanical properties of tire compound. Because the heat expands and contracts, the tire pressure will increase when the temperature is too high. When the tire strength is not enough to withstand the tire pressure, a puncture will occur.
