ABSTRACT:
A loose terrain traction assist device for wheeled vehicles includes a generally frusto-conical structure having a proximal portion with a diameter smaller than an overall diameter of a tire of a vehicle, a distal portion that extends outwardly from the wheel, and an outer surface defined between the proximal portion and the distal portion. The traction assist device also includes an attachment arrangement for releasably coupling the frusto-conical structure to a wheel assembly of the vehicle, such that at least part of the frusto-conical structure is adapted to engage with terrain during operation of the vehicle in loose terrain and to not engage with terrain during operation of the vehicle on normal terrain.
