Wheel load is also called max load. It's the weight that a wheel is able to afford. Usually the max load of a wheel should be around 30% of the total weight of a car. The three performance tests of wheels ( impact resistance test, bending fatigues test and dynamic radial fatigues test) are based on the max load. JWHEEL lab is equipped with completed testing facilities, and is able to run different tests according to the customer's requirements.
