High temperature will cause tire pressure to rise, is it more likely to cause a puncture?
High temperature causes the tire pressure to rise, which is more likely to cause a puncture
After long-term use of the brake, the brake drum will gradually generate high temperature. Since the truck tire valve is close to the middle of the inner side of the tire rim and close to the brake drum, the high temperature generated by the brake drum will cause the rubber at the bottom of the valve to expand and deteriorate, and the sealing performance will deteriorate. Those trucks that often drive in mountainous and hilly areas, because the brakes are often used for a long time, the sealing performance of the tire valve is generally poor, so the probability of tire blowout is higher.
Damage to tires should be cautious, safety performance is not guaranteed
Internal tire damage refers to tires repaired due to sharp punctures or valve leaks. The sealing and load capacity of the repaired tire is much lower than that of the unrepaired tire. The internal tire repair part of the repaired tire usually has a rubber gasket, whose function is to repair the external tire puncture to avoid the repaired tire "packaging" at the external tire puncture ". However, such a gasket protruding from the inner surface of the tire casing may wear the repaired portion of the tube under load. If you often overload driving or encounter road bumps, tires are easy to burst.
If these gaskets are not firmly pasted, or the surface of the gasket is not smooth, it is easy to "bite the tire" phenomenon, which can easily cause the tire to burst. It is suggested that the card friends should repair the tires and use them as spare tires or rear tires as much as possible. Try to use new tires on the front wheels.
Cold water cooling is not advisable, hot and cold easy to burst tire
After driving at high speed for a long time, the tires will heat up. If the heat is not released in time, the tire temperature will rise. Excessive heating (more than 95°C) may cause the tire to delaminate until the tire bursts.
Most trucks are now equipped with a shower system. It is recommended that card friends turn on the air pressure shower to cool the tires when setting off. Don't wait until the tire temperature rises before turning on the shower to cool down. If the tire temperature is too high, use shower cooling. At this time, the external temperature of the tire drops, causing the rubber to shrink, and the internal temperature and pressure of the tire remain high, resulting in different internal and external stresses of the tire, which can easily cause tire blowouts and brake pot bursts.
