The rolling wheel adopts a two-piece product structure, there will be no accidents in which the retaining ring is flying out, and the vehicle is safer to use.

The dynamic unbalance of the rolling wheel is only equivalent to 20% of the steel wheel, which improves the ride comfort of the car.

Rolling wheel adopts advanced technology such as rolling type and spinning, which can reduce weight by about 30% compared with the steel wheel of the same specification, effectively reducing the weight of the wheel.  With the use of tubeless radial tires, the fuel consumption of the car is reduced by 6%-7%, which makes the car more energy-saving and environmentally friendly.

no inner tube has no inner tube, heat transfer is even, and heat dissipation is fast. At the same time, if the sharp object is put into the tire while the car is running, the tubeless wheel will not be out of control due to sudden air leakage and cause a traffic accident.

The speed of the steel wheel is generally 80KM/H, while the tubeless roller has more than 120KM/H.
