A method for providing additional tractionability to a vehicle tire (20) for mitigating slippery road conditions such as ice and snow. The main embodiment for the main embodiment uses three cleats (26) per tire (20) and a cleat hub (28). Chain welts (32) and adjustable bungee cords (30) complete the install to form a contiguous unit gripping around the perimeter of the tire (20). All of the individual parts are lightweight for easy distribution to the tires (20) needing traction. They are easy to install. They are quick to install at roughly five minutes per tire (20). They are also both easy and quick to dismantle. Being solid bodied members, they are easy to keep clean by quickly hosing them down and they stack up for easy storage.

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.

A commercial chain block system is disclosed herein including a block assembly including an elongated platform supported by a first-support-leg, and a second-support-leg extending lengthwise along opposing sides of the platform. The first-support-leg and the second-support-leg have a ramp at one end forming a 45 degree angle. The platform, the first-support-leg, and the second-support-leg are configured to support a tire of a vehicle upon a top-surface of the platform and assist in installing chains on tires of commercial vehicles.
