The rubber tire traction device comprises two lengths of transversely spaced apart link chains and a plurality of cross members extending between the chains. Each cross member has a central portion to contact a tire tread portion and a pair of end portions, each of which has at least one tongue which is secured to a particular single link. In one embodiment, each end portion of the cross member has a second tongue to provide with the first tongue a pair of outwardly extending tongues, a recess being located between the tongues. One side portion and portions of generally arcuate end portions of the particular single link are secured to edges of the recess. Adjacent links interconnecting the particular link also enclose reinforced portions of the particular link and tongue secured together with sufficient clearance to permit hinging thereabouts. In alternative embodiments, the tongue of each end portion has a width defined by space between side edges of the tongue, and a thickness which permits the tongue to be fitted between and secured to side portions of the particular link. The tongue is positioned in the particular link to provide clearance between the tongue and the arcuate end portions of the particular link so that adjacent links interconnected directly to the particular link can swing thereabouts.
