Abstract
A dual tire chain block for adding and removing chains to dual tire trucks includes a block base having a front side sloping from a bottom side to a top side to form a front ramp. A pair of chain mounts is coupled to the inner side and the outer side proximal the front side. A capture chain is coupled to the pair of chain mounts. The capture chain extends between the pair of chain mounts to form a U-shape adjacent the front side of the block base. The capture chain is configured to be driven on by a truck to prevent the block base from slipping away as the truck tires climb the front ramp to rest an inner tire on the top side to elevate an outer tire to receive or remove a snow chain.
