Claim:
1. A traction device for providing increased traction of a tire having a shape and being on a poor tractional surface, and for widening under, and cupping to the shape of, the tire by compression to increase surface area engaging the poor tractional surface to increase weight distribution for the increased traction of the tire, said traction device comprising: a) a base; b) a top cover; and c) a plurality of endless chains; wherein said top cover is affixed to said base; wherein said top cover is for the widening under, and the cupping to the shape of, the tire by the compression to increase said surface area engaging the poor tractional surface to increase the weight distribution for the increased traction of the tire; wherein said base has a pair of long sides; wherein said base has an upper surface; wherein said base has a lower surface; wherein said base has a first plurality of through bores; wherein said base has a second plurality of through bores; wherein said second plurality of through bores of said base are formed into groups; wherein said base has a plurality of traction blocks; wherein said traction blocks of said base are for the increased traction of the tire on the poor tractional surface; wherein said top cover has an outer surface; wherein said top cover has a first plurality of through bores; wherein said plurality of endless chains are for the increased traction of the tire on the poor tractional surface; and wherein said plurality of endless chains extend continuously through diagonally opposed pairs of the first plurality of through bores of said base and continuously through pairs of said first plurality of through bores of the top cover that are aligned with said diagonally opposed pairs of said first plurality of through bores of said base.
