The alloy wheels are the important axle parts the part in the center, equipped with axle parts, connected brake drum (or brake disc). The alloy wheels are set in the shaft tube with the bearing or journal on the knuckles.
The alloy wheels from the manufacturing process are mainly divided into two kinds of casting and forging. Casting alloy wheel is usually aluminum, and aluminum forging alloy wheel is also coupled with titanium. In general, the racing cars use forging alloy wheels because of the strength. The first grand forging ring for racing car is equivalent to half the weight of our ordinary casting ring, the lighter weight, the smaller loss of power cars, and the faster speed.
Another index of alloy wheels is the difference between pitch and offset. The pitch is the location of screws, while offset reflects the distance from the screw surface to the wheel centerline. The requirements of good alloy wheels are: density, morphology round, small thermal deformation and strength.
The replacement of alloy wheels can be convenient to some people to upgrade their own cars, with bigger alloy wheels, but the tire diameter as the same. Although the tire's flat law is larger, the car's horizontal swing is smaller and stability improves, the car loses its comfort.
The match between the tire and alloy wheels is like the clothes and shoes. They may make your car more beautiful, more comfortable, and more attribute.
