A time when the summer heat, car tires under high temperature, become very restless, tire blowout accidents have occurred. The data show that more than 40 percent of traffic accidents and tire related. Tires, the car’s handling, comfort, acceleration has a considerable impact on the important parts that pertain to life safety. Therefore, the height of summer, tire maintenance is particularly important. Recently, many owners have to call “car 114″, asking how to prevent puncture, in the summer tire conservation. Today, we invited the Gar Hyundai Motor conservation experts, Mr. Lu Jingen Weapon for the majority of owners of summer safe driving.
Q: What factors lead to easy flat tire?
Expert Q & A: Generally speaking, flat tire due to tire wear is severe, causing carcass too thin, continue to heat the tire internal At this point, it is easy to object punctured, coupled with the weather overheating, which occurred in a puncture. In addition, the tire burst is also related to several factors.
1, tire pressure. If the tire pressure is easy to make the tire sidewall bending and breaking burst. If the road inflated, due to Tire Valve wear and dust caused by a flat tire, the tire internal tire pressure is too low, can easily lead to a puncture.
2, the tire pressure is too high. Allows the tire defects (such as the site of injury) burst, so the situation is more common in the hot summer weather or prolonged driving. Summer road surface temperature is often above 70 ℃, affected by temperature, the gas inside the tire will be self-inflating tire pressure rose from 2.3 kg to 3 kg for a long time in hot summer driving a car, damage or existence of a weakness in the tire It is easy to tire pressure is too high causing a puncture. In order to ensure the tire pressure, it is recommended nitrogen in the summer, filling pressure should be reduced by 10%. Long high-speed driving, after driving some distance, in the shade to cool the tires. Midday hot while driving, should be appropriately reduced speed.
3, overloaded vehicles. Overloading of the vehicle tire the harm is self-evident, especially on the highway overloading of large trucks, and more prone to puncture the accident.
4, high-speed passing of sharp objects. Vehicles at high speeds, the friction of the tire and road on a sharp stone or other sharp objects cause leaks, and then a tire failure is more common.
Q: daily driving should pay attention to what matters to prevent puncture?
Expert Q & A: flat tire is a complex phenomenon of tire destruction, there is a certain chance, but to strengthen the day-to-day maintenance can still be effective in preventing puncture.
A timely replacement of tires. Summer temperatures will accelerate the wear and tear of aging of tire rubber, wire layer strength decline, general tire tread trench raised mark, is to remind owners to change the tire in a timely manner.
2, positioning, balancing certain essential. Replacement or installation of tires, wheels to the car, the orientation angle and quality of distribution and will change, the most direct impact is that the tire uneven force are serious, individual tire tread wear, the summer driving or high-speed driving for a long time easily lead to puncture. Owners must regularly to the car wheel alignment and balance.
Three, four transposition, extend tire life. Car front wheel hit the steering wheel’s sake, wear speed faster than the rear wheel in order to extend tire life, rotate the tires on a regular basis in order to balance the wear of the front and rear. General diagonal swap ways to make the tires wear evenly.
And maintain a normal tire pressure. Summer tire pressure is easy to exceed the maximum value of continuous driving under high temperature or non-normal leakage will cause the tire pressure variation and puncture, so they give the car tires filled with nitrogen gas is the right choice. Nitrogen is an inert gas, is not easy to change as the temperature changes. In addition, sufficient nitrogen can also prevent tire natural oxidation and cracking.
Often remove stones or foreign objects in the tread grooves, so as not to tire tread deformation. Check the tire sidewall whether cut, stabbed, and whether the exposed cord. If so, should be replaced. In addition, frequent driving on the highway must be on the tires regularly carry out transposition. Deserves special attention, daily tire inspections should also include the spare tire.
