A traction-increasing attachment for driven vehicle-wheels has at least one L-shaped rigid member for extending diametrically over the face of a disk-type wheel and has a cleat-like extension extending transversely over the tire tread of the wheel. A quickly and easily mountable and demountable support member diametrically spans the face of the wheel and has anchoring fingers receivable in conventional slots in the wheel adjacent its tire-receiving rim. The support member can be formed of two length-adjustable straps or it can be a slightly bowed single strap, which, when straightened by being assembled with the wheel, has its ends thereby extended to anchor in the wheel slots.
