Blowout is an accident and dangerous situation when driving at high speed. The concrete performance is the sudden tremor of the steering wheel, and the "bang" loud noise followed by the head of the car. The so-called tire burst actually means that the tire loses most of the air in a very short time, thereby affecting normal driving. If it is the front wheel blowout: must hold the steering wheel, adjust the head, the action should be gentle, can not beat the steering wheel again and again, can not step on the brake, and then slow down the steering wheel after the speed of the vehicle gradually slow down, then the warning triangle plate is erected after the car, to prevent the two accidents. If it is a rear wheel blowout: the car will take on an unstable state and produce a slight force that makes the car inclined to the side of the tire. At this point, the car should be slowly stopped by oil recovery. Here we should emphasize that unlike the front tire burst, because the rear wheel does not have the guiding function, and the rear wheel bearing weight of the general car is relatively low, the rear wheel blowout is not very dangerous, just hold the steering wheel. 1: to improve the understanding of tire safety, usually check the tires, especially before the high speed, we must do a good and careful inspection, besides the tire pressure, it is also necessary to observe whether there are cracks on the side of the tire, the condition of the tread wear, and find out the hidden danger in time. 2: regular tire transposition is carried out to keep the tire on the same car evenly. The vehicle should make one tire transposition every 5000 km of the vehicle, and make a four wheel positioning per 5000~10000 kilometer to avoid abnormal excessive wear and not allow the same type or new and old tires to be installed on the same axis. . 3: regular correction of wheel balance, wheel imbalance over the standard, high speed driving will produce high frequency oscillating, causing tire wear, not conducive to traffic safety. After tire repair, action should be taken to balance detection and adjustment. The tire unilateral dynamic balance should be less than or equal to 40 grams.
