Now the streets are all kinds of vehicles, the shuttle into the city. So travel by car owners who need to keep in mind, sometimes too easy to scratch is likely to occur with other vehicles, bump such minor incidents, with respect to the prevention of these accidents is relatively easy, for a number of small sharp objects scattered on the road that some of it is difficult to prevent. Once the car during driving, the tires were slashed to screw such as sharp objects, it is likely to lead to a puncture, but while the owners go to garages or 4S shop maintenance, staff often will miss you sell explosion round, then What is the run-flat tires, which it has the advantages of flat tires really that magical? Flat tires which there is no need to install it?
flat tire, its official name should be called – run-flat tires, from the literal meaning can know the deficiencies of this tire in tire pressure or leak case with the help of a vehicle over a period of distance and speed within the normal travel. And ldquo; anti-puncture rdquo; the name is actually using this tire manufacturers and tire manufacturers hype for this car tire. In other words, the so-called run-flat tires is the tire in case of leakage, even if the air pressure inside the tire completely lost, can continue traveling at a speed of 80 km / h, so you have time to reach the nearest support safe driving car repair.
The spoken above, it can be concluded several advantages flat tires:
1) is more durable than a general tire, because the run-flat tire using the enhanced sidewall structure, so its durability is destined better than the average of the tire, and ordinary tire cord composed of several layers is generally made thinner sidewall;
2) which is more secure, is at high speeds puncture drivers fear the situation encountered, because the focus shifted puncture the moment is likely to make the vehicle out of control, a lot of people also lost their lives here, so the choice of tires must be careful. The runflat support and toughness more than the sidewall of the tire in general, so when it suddenly deflated or can make a puncture wheels and tires support the vehicle in conjunction with one another is not too dangerous. And if it is the general experience sudden flat tire or tire deflated, can only rely on the hub to the wheel in contact with the ground, the less support the tire, since the general tire when the tire pressure will not departing from the hub;
3) can be ldquo; branchSupport rdquo; for a long time, but flat tires leak, its situation will not immediately complete vent gas, tires because the tire construction itself is not the same, so it can help you in the leak continued to travel some distance. Even in the case of zero tire pressure, run-flat tires and some good points but also to 80KM h speed / running about three hours, and general tire discouraged discouraged, and you would not even think it will help you run more than a few km so that you find a place to change tires.
Although the advantages projecting flat tire, the disadvantages can not be ignored, which mainly has the following disadvantages:
1) Large flat tire weight. Equipped with anti-riot vehicle tire than the average weight of a lot, if the car is fitted with four flat tires take more than the equivalent of a person’s weight;
2) run-flat tires comfort is not good. Since run-flat tires have been designed to strengthen the sidewalls, the tire thus bound to the comfort of the tire is generally poor;
3) flat tire repair is troublesome, because it is very thick sidewalls hard, very easy get down, even if the machine is too much trouble, if the operation is not good tire wall will cause irreparable harm, and now after run-flat tires were slashed in general will be directly replaced.
Xiao Bian above talked about so much knowledge of flat tires, is to let everyone to form an idea of the true-flat tires, he stressed ldquo; flat tires rdquo; in fact, not not a flat tire, but the car still discouraged after a few hours can last voyage, to avoid a general tire ldquo; a vent in the end rdquo; shortcomings, but also bring convenience to the owners. In particular, it reduces the chances of high-speed driving on a flat tire caused the sudden danger.
Although ldquo; flat tires rdquo; not as magical publicity, but it’s role is great, from the car in terms of safety, if the owner is the budget enough, I suggest that owners of small or explosion-proof installation tires, especially high-speed or poor road conditions often run lots of friends, run-flat tires is very useful, but still have to remember not to panic after a high-speed puncture, do not slam on the brakes or steering wheel too hard to make such a suicidal move, certain to respond calmly, oil revenues gradually slow down, grip the steering wheel, or flat tires can save lives.
