A tire traction device includes at least two continuous circumferentially extending tread groove bead members adapted to nest within respective circumferentially extending tread grooves of selected vehicle tires. A plurality of circumferentially spaced transverse traction elements are integral with and connect the tread groove bead members. The traction elements are configured and dimensioned to overlie the tread of the tire and to thereby improve the traction thereof. Preferably a circumferentially extending traction element is provided intermediate the tread groove bead members and the transverse traction elements are arranged in circumferentially spaced pairs connecting the tread groove members and the circumferential traction element.
