How can the car tire drum bag, in the end is what reason?

Kumho Tire recall has not yet subsided, with South Korea manufacturer Hankook tire has been pushed to the cusp of the all the owners, drum kit? Fracture? The quality of automobile tires has caused wide attention of people. And as the recent case of consumer complaints more, Tire Drum package should be considered the most common phenomenon of tire damage. In this regard, some users have raised questions: whether the tire drum kit and rubber quality related? Today, we will look at the tire drum package in the end what is the cause? How should we prevent it?

Basic structure of tire

Tires are the most important parts of the car, it looks very simple, in fact, is very complicated. Tire has a variety of classification, the most common pneumatic tire has two kinds of bias tire and radial tire, they are according to the carcass ply laminating form different respectively named. We use the radial tire commonly used car for example, to understand its structure:

1 tire tread: 1 thick layer of rubber, provides a contact interface with the ground, but also has the drainage and the old performance.

2 the crown with a bundle: a double or 3 layer to strengthen the belt with a beam with a vertical direction of the flexibility and a high degree of lateral rigidity, providing steering force.

3: the side of the tire sidewall contain and protect the carcass ply, and carcass ply is the function of the tire fixed on the rim.

4 tire ring: its internal wire coil can be firmly fixed on the rim of the tire, so that it can be combined together.

5 airtight layer: it ensures the tire has good air tightness, and maintains the correct tire pressure.

Pneumatic tire is mainly composed of the rubber parts and ply, don't look at appearance tyres are made of rubber, but the rubber in the tire carcass plays only a combination of matrix components, sealing, wear-resisting, anti puncture and the buffer role, truly "output" is hidden inside the rubber curtain cloth. The curtain is used as matrix material in the tire, the tire is the main stress components. That is to say, the tyre inflation pressure and vehicle load, prevent inner tube is inflated after the expansion, to protect the inner tyre from mechanical damage, transfer traction force and braking force and the rough work, almost all borne by the cloth. In this regard, the rubber output and not appear in public.

Fit the form of radial tire and oblique tire cord is different

With bias tire ply cord cross fit different, radial tire cord is similar to the radial shape, due to the full by warp to produce strong and weft only connecting the adjacent warp, gently pull will be disconnected, if alone cord warp, weft and rubber strength, in charge to gas or driving, braking, radial tire extremely easily from the warp is disconnected. In order to eliminate the weak link, the material of radial tire cord fabric layer are made of steel wire, and between the tread and carcass ply layer increased composed of a plurality of layers of cord of the belt beam layer "(ply and belt beam layer for steel wire for all steel tire, belt layer is a fiber cord material for semi steel tire), so as to ensure that the tire can withstand all kinds of force.

The ultimate mechanism of the phenomenon of the tire bulge caused by the rupture of the tire cord

There are many reasons for the phenomenon of the drum. In general, the occurrence of the phenomenon of tire drum is due to the strong impact of the accident, which leads to the severe deformation of the tire. For the radial tire, the sidewall part is the weakest place, due to the absence of the belt beam layer of protection, in the event of a serious deformation will cause side of the tire cord rupture, then the air inside of the tire will from fracture at the top, forming drum kits. The main factors which cause the phenomenon of the tire drum is the bad air pressure, bad road, the accident and the careless driving way. In addition, often on the curb and parking tire rub obstacles also may cause damage to the tire wall, "bulge".

And if the tire large quantities of drum bag, is largely due to the quality of the problem, due to the tire manufacturing process, the level of the curtain line is not enough to hang the glue, or because the colloid itself contains high moisture content. According to the relevant provisions of the industry, the normal use of the tire is the date of the factory 3-5. If in this period of time, not because of the special causes of the collision caused by the drum kit, then the quality of the tire may exist problems.

Does the tire drum package affect the driving?

So, whether the tires will affect the traffic? Is there any danger? Here to remind you, side of the tire "bulge", not only influences the traffic, but also the risk of puncture is driving major accident hazards. Therefore, if there is a drum kit, and resolutely can not use the drum kit tires. Must immediately go to the regular tire shop for professional testing and replacement.

How to prevent tire drum kits and tire regular inspection

Excessive pressure or too small to have a negative impact on the tire. Pressure is too large, the tire to harden, tread and the contact area decreases, affect the handling and ride comfort, easy abrasion of a tire; the air pressure is too low, soft tires, vehicle fuel consumption rises, tire when it hits easily between the obstacle and the rim produced shear stress large fracture. So how to avoid the occurrence of the phenomenon of the drum, and prolong the service life of the tire? Here to tell you some tips:

First: when installing the tire, please go to the professional tire shop, use the tire professional installation equipment and professional installation program to fuck
