Firstly, the material of the hub is divided into iron hub and steel hub, which are used more in trucks or buses. Moreover is now the car commonly used aluminum wheel hub, in the aluminum wheel hub is divided into forging and casting two kinds, the strength of forging wheel hub is many times of the casting wheel hub, to exaggerate the point directly on the track can run, the current market is 99% of the wheel hub is cast. Forging and casting can be distinguished only by the use of instruments to see the molecular structure, or by destructive testing.

Next, the surface treatment of the wheel hub, divided into coating (paint), electroplating, polishing (no protective layer), there are advantages and disadvantages, not to mention here.

Again, the diameter of the wheel hub on the impact of driving, because the diameter of the wheel is fixed, the larger the diameter of the wheel wheel tire wall is the more flat, in the acceleration, braking, over the bend when the deformation of the tire is smaller, the more stable driving, in case the tire diameter change is not a great deal of harm will be reduced.

Finally, the wider the hub, the better the handling.

I won't say much else, but wheels and tires are the most important parts of a car, but they are often overlooked...
