Abstract: An improved method for providing additional traction to vehicles during icy and snowy conditions. Especially in the Rocky Mountain states, where trucks are required to carry chains during the winter season, the Traction Pad (#6)provides a simpler and quicker alternative. The Traction Pads (#6) stack upon each other, are light-weight, and easily set upon the tires (#1), as they are shaped to the same contour as the tires(#1). Then, they are fastened to the belt (#3) that is already installed at the rim (#2), between the dual tire assembly (#1). The Traction Pad's (#6) ease of install and removal make them ideal in those situations, in wintery weather, on the side of a highway, where the sooner the truck-driver can get back in the warmth and safety of his/her cab, the better.
