The wheels of the ICAR 03 are made of aluminium alloy, which has many advantages:

- Light weight: the density of aluminium alloy is about one third of steel, using aluminium alloy wheels can effectively reduce the unsprung mass of the vehicle, improve vehicle handling and acceleration, and also reduce energy consumption and increase mileage.

- Fast heat dissipation: Aluminium alloy has good thermal conductivity, so the heat generated by the brake system can be quickly dissipated through the wheel hub during driving, effectively avoiding the performance degradation caused by overheating of the brakes, prolonging the service life of the braking system, and improving driving safety.

- High precision: Aluminium alloy wheels have a mature manufacturing process and can achieve high dimensional and shape precision, which makes the wheels better balanced when rotating at high speeds, reduces steering wheel shaking when driving, and improves driving comfort.

- Beautiful shape: Aluminium alloy material has good plasticity and processability, and can produce a variety of complex, exquisite shape to meet the individual needs of different consumers, making the vehicle more fashionable and recognizable.

- Strong corrosion resistance: Aluminium alloy reacts easily with oxygen in the air and forms a dense oxide film on the surface, which can effectively prevent the wheel from being corroded further, making it more corrosion-resistant and with a longer service life.
