Peerless 0231805 Auto-Trac Auto Tightening Light Truck/SUV/Car Snow Tire Chains

The Auto-Trac Self Tightening Traction Chain is a high impact, self-tightening ratchet system that ensures a snug fit and eliminates the need to stop and retighten the chains after installation. The split outside chain with two ratchet connectors allow easy installation without moving the vehicle. Features an aggressive diamond patterned cross-chain designed for superior traction and a smooth ride. The case hardened alloy cross-chains provide extended wear lift over standard link products. Auto-Trac can be installed without moving or jacking up the vehicle! The patented, ratcheting tightening system automatically tightens the chain while driving.

Just connect the inside cable, attach the two outside selftighteners and drive! No additional chain tighteners are necessary or recommended and should not be used. Will meet Class “S” clearance requirements on SUVs and pickup trucks, as well as normal passenger cars (matching the capabilities of most of our “Z” cable products). This is possible because of a highly effective, patented tensioning system. Auto-Trac cross member links are made of manganese alloy steel, allowing them to be shorter, narrower and lighter than conventional cross members. This reduces “fly-off” during operation and provides more gripping points.

The low-mass “D” cross section of the links also contributes to longer wear because the impact of the cross members on the road surface is reduced and the surface area contacting the road is increased.
