Q:How many layers are the tires of the car?

The meridian is the tyre technique. Almost all tyres are now using this technology or higher than this technology. What you say is that the car tires are generally divided into three layers. In addition to what you said, there is a coat of outer rubber. You can see the picture below.

Q:What's the difference between a truck tire and a set?

There are three parts of inner tube tyre, which are made up of tyre shell (called shell), inner tube and cushion beltThe three parts add up to a set of tires, and only the case is called a tire

Q:How to distinguish the tire grades?

Each tire side is engraved with the tire speed symbol (also called speed level), corresponding to the speed symbol, you can know the maximum speed of the tire

Q:What tools do you need to fill the tires?

It is best not to fire up because now is the best way to tire rubber in tire glue sheet can try the film if mushroom is large enough

Q:What is the height of the section height of the automobile tire? Do you have pictures?

Standard Specification for general radial car tyres includes the following:Section width of tyre, unit mm.Tire aspect ratio.Tyre structure mark.Rim diameter, in inches.Load index.Speed symbol.The nominal height to width ratio of a tire refers to the ratio of the section height of the tire installed on the theoretical rim to the width of the section.

Q:What minimum tread depth is required by law?

Therefore, the depth of the tread pattern has great influence on the driving of the car, whether the tread pattern is too deep or too shallow is not good. The objective law is that the patterns will be smaller and smaller in use. In order to ensure the effectiveness of the pattern effect, all countries in the world on tire wear limit has made clear regulations, and in the tire shoulder along the circumference of the plurality of parts mold carved tire wear limit alarm mark, when the marking pattern has been removed, revealed a narrow horizontal strip of light tread, so as to alert the driver. The tire has to be replaced time.

Q:Why are the outer tires behind the car worn?

Within 20000 kilometers, the front wheels are interchanged (about to the opposite) every 5000 kilometers. The rear wheels are the same. 20000 km, front and rear wheel down, and every 5000 kilometers of front wheel swap, the same rear wheel. In this way, each tire runs 20000 kilometers in front and back, during the period of reciprocal pouring. The normal life of tires is about 6~8 kilometers, generally speaking, the driving wheel wear will be more. Under normal circumstances, every twenty thousand kilometers of tire transposition, choose the same side before and after transposition or transposition transposition is more commonly used, in order to achieve the purpose of uniform use of tires.

Q:What is the reason to run over the truck tires

Did you have a flat tire or something like that?. If there is, it may be that the wheel hub has become out of round after a flat tire, which is also a reason..

Q:What's the use of tyres, high pressure tyres and low pressure tyres?

Low pressure tire has good elasticity, wide cross section, large contact with road, thin wall and good heat dissipation. These characteristics improve the vehicle ride comfort, steering control stability.High pressure tyres can increase loads, usually for carts.Because of the development of skeleton material and tire design, the tire load increased gradually, and the air pressure increased accordingly, while the cushioning performance was similar to that of the original low pressure tire. Therefore, the high-pressure tire and low pressure tire can not be adjusted according to the inflation pressure.

Q:The tires are different. Do you have anything to do?

Tire is one of the most important components of automobile, its main function is: all the weight support of the vehicle under car load transfer; traction and braking torque, ensure the adhesion of wheel; vibration and impact mitigation and absorption while driving, prevent the auto parts by the violent vibration and early damage to adapt to the high speed performance of the vehicle, and reduce running noise, ensure driving safety and handling stability, comfort and energy saving economy.
