Abstract: A tire traction device which may improve or provide tire traction for various vehicles is described. The tire traction device includes a board having a first end and a second end, wherein the first end has a curved edge and the second end has a slanted edge. The board may include more than one section. The board includes a rough or grooved top surface, and a plurality of spikes extend from the bottom surface of the board. The tire traction device may also include a flexible component attached to the board. The flexible component is designed so that it may be drawn underneath a spinning tire.

Abstract: The present invention relates to an apparatus used for tightening tire chains. One embodiment of the present invention includes an outer portion and an inner portion. The outer and inner portions have a plurality of first and second apertures, respectively. A plurality of arms are secured onto the inner portion and extend through the second aperture and then through the first apertures. The arms have a first end which is adapted to be secured onto the inner portion, and a second end which is adapted to secure to a tire chain. A bar variably couples the outer portion and the inner portion. The distance between the outer and inner portions adds or subtracts tension in the arm which correspondingly adds or subtracts tension in the tire chain.
