Performance wheels, such as ESR wheels, have several advantages over other types of wheels. They can be very efficient and balance this with safety and performance. They are also able to be engineered with several types of colors. The success of performance wheels comes from how they are tested.
Stiffness-to-Weight Ratio
The stiffness to weight ratio is the measure of the efficiency of a material's mass. In an axial mode, it is measured by tensile modulus divided by density.
