The aluminum alloy rim has better high-speed stability, the wheel will not shake after the speed comes up, the aluminum alloy rim is lighter in weight and has better heat dissipation performance. The iron rim is easy to tremble when driving at high speed, because the iron rim is stamped and the mass balance weight is not very uniform.

Aluminum alloy rim has better heat dissipation. When the car runs for a long time, the tires will heat up, and so will the brake system. Aluminum alloy wheels have better heat dissipation performance than iron wheels, which can help brakes and tires dissipate heat faster.
