Traction device for vehicles

A wheel mountable device for increasing the traction of a tire on a road surface comprising:

• a plurality of traction elements secured together in an endless chain,
• said elements comprising a plastic body each having an elongated traction member having generally planar inner and outer surfaces for extending laterally across the width of the tire and a pair of fastening members formed to extend laterally one across each end of said traction member,
• each of said fastening members being arcuate in shape to fit around and conform to sidewalls of the tire,
• means for detachably mounting at least one stud of wear resistant material to at least one traction member of at least one of said elements,
• said means comprising a bracket for wrapping around a part of said inner surface of said traction member,
• said stud being secured to said bracket for extending through said traction member laterally thereof and outwardly of its outer surface, and
• fastening means attached to said fastening members of said traction members for releasably securing said traction elements in an endless chain for mounting around the circumference of a tire,
• whereby the inner surfaces of said traction members abut the outer periphery of the tire such that as the tire rolls along a road surface the traction members contact the road surface with the stud providing added traction for the tire.
