Wheel repair
There are few maintenance stores in China that can be done in China. Among them, the largest wheels renovate the maintenance store is the king of the bell. One -in -one national wheel tire 4S shop.

Advantages and disadvantages
The aluminum alloy hub for automobiles is based on aluminum alloy. Its manufacturing process is divided into two types: casting and forging.

The aluminum alloy wheels are divided into the following four characteristics:

1 Improve the comfort of driving. The aluminum alloy wheels have the metallic characteristics of absorbing vibration and rebounding. The size accuracy of the processing of the CNC machine tool, high real roundness, small switched jump, good balance, so that the car is smooth and comfortable.

2 Normal driving, saving fuel. Due to the weight of the aluminum alloy wheels, the rotation inertia of four -wheel rotation is reduced, the acceleration of the car is improved, and the energy needs of the braking energy are relatively reduced, thereby reducing fuel consumption.

3 Improve the safety of driving. The scattered temperature coefficient of aluminum alloy wheels is two to three times that of ordinary steel wheels. In addition, the structural characteristics of aluminum alloy wheels can easily disperse the tires and brake systems in the air in the air. In the case of continuous braking during long -term driving, it can keep the wheel system properly temperature.

4 Improve the beauty of the entire vehicle. The exquisite design of the aluminum alloy wheels and diverse shapes can achieve the combination of the hub to show perfect. Improve the aesthetics of the vehicle.

5 Improve driving stability. The tires are widening and increasing grip, braking performance, and effectively improving the driving handling and driving fun.

There are certain disadvantages of aluminum alloy wheels, as follows:

1 High cost. It takes a lot of cost to replace the alloy wheels.

2 The modified vehicle shock absorber is slightly hardened. Because the flat ratio of the tires after modified is lower, there is a slight feeling of reducing vibration reduction and hardening.

3 After increasing the size of the wheels, it will increase slightly in terms of fuel, but there is no change in fuel for replacing brand -name tires.
