Auto‑Trac® snow chains feature a patented Automatic Tightening system that works with centrifugal force when driving to automatically center and tighten the chains onto your tire.
Best Durability in Link Style Chains: Low-mass “D” cross sections reduces impact on road surface. Case hardened manganese alloy cross-chains provide extended wear life over standard link products.
Self-Tightening Installation: Split outside chain allows easy installation. The high impact, self-tightening ratchet system ensures a snug fit and eliminates the need to stop and retighten the chains after installation. The two Patented Auto Trac® tighteners allow easy installation without having to move the vehicle.
Better Safer Traction and Smoother Ride: Auto Trac® meets Class “S” clearance requirements. Alloy links allow for lighter crossmembers and lower profiles reducing vehicle vibrations. Diamond pattern provides more gripping points for better lateral traction, shorter stopping distances, and turning radius. Auto-Trac provides better handling and steering in and out of corners even while braking.
