Car owners need to pay attention to the cooperation of tires and hubs everyday.

The cooperation of tires and wheels is just like the matching of clothes and shoes for a car. With a good combination, it can complement each other. Most of the limousine wheels are made of aluminum alloy materials. This kind of wheel looks beautiful, but it is also delicate. To maintain the appearance of the hub, besides taking extra care to prevent accidental damage to the hub during driving, the hub must be regularly maintained and maintained. Another distinguishing indicator of the hub is the difference between hole pitch and eccentricity. The hole distance is simply the position of the screw, and the eccentricity is the distance from the hub's face (fixed face) to the centerline of the hub.

In order not to damage the protective layer on the hub surface itself, paint brighteners or other abrasive materials cannot be used on the hub. Wash the sand particles on the surface of the hub and the dirt that can easily damage the hub. The inner and outer surfaces of the hub are treated with anti-acid cleaners. When the alloy protective lacquer is damaged, if there is a scratch on the hard object during driving, the alloy hub should be repaired and repainted as soon as possible. In general, the strength of the forging circle is large, and the racing car uses a forging circle. The first forging circle for racing is equivalent to half the weight of our ordinary casting circle. The lighter the weight, the smaller the power loss of the car and the faster it runs. The hub is mainly divided into casting and forging from the manufacturing process. Generally, the casting circle is aluminum, and the forging circle is made of aluminum and titanium. The wheels can be replaced by new ones. Some people upgrade their cars and use bigger wheels. However, the outer diameter of the tires does not change, the flat tires of the tires become larger, the lateral swing of the car becomes smaller, and the stability improves. What is lost is comfort.
