What do you mean, wheels with rims don't? Is it necessary to change the aluminum ring for the steel ring?

If wheels are classified according to materials, they are mainly divided into steel wheel and aluminum alloy wheel. Steel wheel hub is a kind of steel wheel, and steel wheel hub does not mean that steel wheel is not used. The reason is that the wheel hub of steel ring is relatively heavy and has large inertia, which is not conducive to fuel saving. In addition, due to structural problems, the cooling efficiency of steel wheel hub is not as good as that of alloy material, which is not conducive to braking heat conduction and may reduce braking efficiency.

Vehicles using rims should not be parked for a long time to avoid slight deformation of rims and irreversible situation.

If it is a new car, there is no need to replace the steel ring with an aluminum ring. In fact, steel wheels and aluminum wheels have their own advantages and disadvantages. On the whole, it is impossible to decide which one is better, mainly because the owner chooses the wheel hub that is more suitable for his car style and actual car use according to his actual situation.

Let's look at the advantages and disadvantages of steel wheels and aluminum wheels.

1, in terms of weight, aluminum alloy is much lighter than steel wheels, which not only reduces the weight of the car body, but also effectively saves fuel consumption. Steel wheel hub is relatively heavy, unsprung weight is also large, and fuel consumption is not low.

2. In terms of heat conduction, the steel wheel hub has low heat dissipation efficiency and obvious brake attenuation, even if it is serious, it may cause brake failure. However, aluminum alloy wheels have better heat conduction or heat dissipation.

3. In terms of repair, the toughness of steel hub is better than that of aluminum alloy, and it can also be repaired by impact deformation. However, the aluminum alloy wheel hub may break after impact and cannot be repaired.

Many people think that aluminum alloy wheels will look better, so they want to replace the original steel wheel hub, but we should proceed from reality, not just from appearance.
