1. The wheel disc use the patent design of “Bridge-Arc wheel” shape to improve the strength and loading capacity, and reduce the disc split from the vent hole.
2. The patent design of Ridge improve the strength of wheel rim effectively.
3. The using of high strength special steel for wheel and the shape of Bridge-arc, 20% wheel weight reduction, 12% increasing of strength.
4. The patent design of Big Radian on the flange prohibit the tire ruing out of the rim when the vehicle turns sharply.
5. The unique structure of fan shape improves the heat dissipation (the experiment proved that the temperature of the Bridge-arc wheel’s tire is 2 degree less than that of the normal wheel, when the temperature of tire reduces 1 degree it can enable the tire to work more than 5000 to 6000 kilometers. If we using the Bridge-arc wheel, it can enable the tire to run more than 10,000 kilometer.
