Bánh xe skateboard (Skateboard wheel)

"Skateboard wheels" are the wheels used in skateboards. Skateboard wheels are typically made of polyurethane and feature bearings that allow the wheels to rotate freely on the axles (trucks). Their shape, hardness, and size can vary depending on the rider's preferences and the type of riding they are intended for. For example, larger and softer wheels are better suited for riding on rough surfaces, while smaller and harder wheels are more suitable for tricks and skate park riding.
