Material: EV wheels are commonly made from aluminum alloy, which offers a balance of strength and lightweight design, improving efficiency and performance. Design: Wheels can be designed for aerodynamics to reduce drag, improving the vehicle's energy efficiency. This could involve sleek, streamlined patterns or closed-off designs to minimize air resistance. Size: The size of EV wheels generally ranges between 15 to 21 inches in diameter, depending on the type of vehicle. Larger wheels can enhance handling and appearance, while smaller ones might offer better range due to reduced energy consumption.
