Is a puncture really so damaging?

The harm caused by the explosion of automobile tires can be very big or small. What kind of harm will the truck tires explode? On September 25th, the owner repaired a car stall on the side of the road in Jiangning District, Nanjing. The owner unloaded a large trailer truck tire and stood on top of the tire to repair tires and inflate. The tire suddenly exploded and the owner was blown up to 56 meters high. Fall to death.

According to a mechanics expert, the car's maximum tire pressure is 10kg/cm2, which is equivalent to the pressure on the bottom of a 30-story building. Assume that a tire with a tire pressure of 5 kilograms per square centimeter is instantaneously exploding, and a short-distance shock wave is enough to break the bones of a person. The power of a large truck tire is no less than that of a grenades. The smaller the breach is, the greater the impact is. The explosion point is within a dangerous area of ​​nearly 10 meters.

Unlike truck tires, truck tires are not vacuum tires, but have tires and inner tubes, like a larger version of a bicycle tire. Due to the thick tire wall of the truck tires and the steel wires inside, the tires are generally not punctured. If a puncture occurs, it is basically a problem with the tire, so always pay more attention to checking the truck's tires to prevent explosions and avoid unnecessary trouble.

The normal tire pressure of a truck is generally within 10-12 pressures, and friction between the tire and the ground during driving causes the temperature of the tire to rise. The principle of thermal expansion and contraction will also follow the rise in tire pressure. One can imagine how great the tire blast power of trucks is. Therefore, in order to ensure the safety of driving while driving, you should try to stay away from the cart, keep the distance, and must not be too close to the cart.

The final Xiaobian to remind everyone is, do not think that truck tire explosion is not so great power, not to curiosity to watch the truck tire filling situation, or the consequences would be disastrous.
