Choose The Wheel Hub Correctly And Pick Up Two "Good Shoes" For The Car.

Tires and wheels are comfortable shoes for cars.

Some owners do not attach much importance to the modification of wheels and tyres. This is very wrong. We must know that each vehicle has only four wheels in contact with the ground. All the power of the vehicle must be passed through the wheels, and the safety of the vehicles will also be maintained on these four wheels.

Therefore, tyres should not only be suitable, but also have grip and beauty.

Understand tire signs

The correct use of tires must first know the tires, and the first thing to know about tires is to see the signs on the tires.

For example, 195 / 60R15H, what does it mean?

195 the width of the tire represents 195mm; the 60 represents the aspect ratio of the tire; R stands for the radial tire; the 15 indicates that the inner diameter of the tire is 15 inches, which is suitable for 15 inch rims; and H represents the maximum speed of the tire at 210 km / h.

Some tires are marked with M + S, indicating mud and snow fields. TUBELESS means no tubeless, and TreadWear means tread wear index.

For car tyres, one of the important parameters is the ratio of height to width, that is, flatness, and the smaller the flat rate, the stronger the handling performance.

"If the new tyres are brakes on the brake frequently at the initial stage of operation, they will cause 1 of the tire and 1 of the tire consumption. The phenomenon will not only increase the noise of the tire during driving, but also affect the service life."

Zhang Guoxing, manager of Wanguo tire company, told reporters that during the driving process, we should pay attention to checking the air pressure of the tire regularly, because the air pressure is too high or insufficient, which will cause abnormal wear and tear on the tire, crack on the bottom of the pattern, cord breaking, cord layer delamination, tire blasting and so on.

At the same time, the tire on the vehicle should be placed in place at the right time, so as to keep the tire wear uniform and prolong the service life. If the tire is worn to the wear mark, it must be replaced.

Aluminum wheels become mainstream

The aluminum alloy wheel hub has attracted more and more private car owners' favor because of its beauty, safety and comfort.

At present, almost all new models are made of aluminum alloy wheels, and many car owners also change their original wheels to aluminum alloy wheels.

What are the characteristics of aluminum alloy wheels? What should we pay attention to in maintenance?

"From the manufacturing process, the hub is mainly made of two kinds of casting and forging: the forging hub structure is compact and the strength is better, and the forging hub is lighter than the casting hub under the same strength and the same strength.

But the forging hub has a high cost, and its selling price is much higher than that of the casting hub. "

Zhang Guoxing said that there are many kinds of styles, such as seven spoke, five spoke, multi column, and so on.

Although the shape of aluminum alloy wheels is rich and varied, there are a lot of options to choose from. However, when choosing wheels, owners should not pursue beauty blindly. Complicated wheels or wheel covers are very troublesome when washing cars.

Beautiful, simple and easy to clean is the best.

When the hub temperature is high, it should be allowed to cool naturally before cleaning. It must not be washed with cold water. Otherwise, the aluminum alloy wheel will be damaged, or even the deformation of the brake disc will affect the braking effect.

In addition, cleaning the aluminum alloy wheels with cleaning agents at high temperatures will cause chemical reactions on the surface of the wheels, causing them to lose their luster and affect their appearance.
