Abstract: An expandable wheel (100) assembly attached to a vehicle includes a circular rim disc (200) operable to receive a plurality of drive members (300) about its circumference. The drive members (300) are pivotally connected to the rim disc (200) and expand outward from the rim disc (200) via sliding levers (500) when a rotational force is applied to the rim disc (200). As a result, the drive members (300) increase the ground clearance and enhance the ability for the vehicle to negotiate variable terrain while also increasing the top velocity of the vehicle. The expandable wheel (100) assembly contracts to a circumferential closed position when the rotational force is removed.
