Auto-Trac ®

A Highly Unique Self-Tightening Traction Chain

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 self-tighteners and drive! No additional chain tensioners are necessary or recommended.

Auto‑Trac® 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. 

Chain tensioners SHOULD NOT be used.

Self-Tightening Ratchet

This high impact, self-tightening ratchet system ensures a snug fit and eliminates the need to stop and re-tighten the chains after installation. The split outside chain with two ratchet connectors allows easy installation without moving the vehicle.


Better all-around traction performance and a smoother ride than conventional traction products.


Best durability of any link-style chain for cars and light trucks.


Covered by U.S. and international patents. Auto-Trac® stands out as unique tire chain and was made to offer easy installation, high quality, and peak performance.

Compatibility with ABS and traction control systems

Auto-Trac® provides excellent compatibility with Anti-Lock Braking Systems and traction control systems. Auto-Trac® will work with these braking systems so you can maintain control of your vehicle when heavily braking. With Auto-Trac® you can drive in winter conditions with confidence.

Includes an Auto-Trac® Bag

Included with each pair of chains: Waterproof, illustrated, step-by-step installation and removal instructions, plastic gloves and an accessory kit which contains a repair link and wire ties to secure any excess side chain links. Everything is stored in a reusable nylon bag.
