Semi Truck Tire Chains

How to Install Tire Chains on a Semi-Truck (Step-by-Step)

Installing semi-truck tire chains takes preparation and care. Use the steps below along with your chain maker’s instructions and local regulations.

1. Check local regulations: Confirm chain rules for your route (speed limits, which axles must be chained, etc.). See California’s summary and a multi-state overview: California chain-control basics and tire chain laws by state.
2. Select the right chains: Choose commercial-rated chains that match your exact tire size and duty level. Start with the Tire Chain Size Guide. Examples: 11R-22.5 cable chains with cams and 295/75R22.5 heavy-duty boron-alloy chains.
3. Prepare the chains: Lay each chain flat, untangled, with traction side out. Verify all fasteners are present. Keep essential gear handy: tire chain tools & accessories, a cam tightening tool, and (if needed) tensioners & adjusters.
4. Position the chains: Center the chain over the tread of the first drive tire. Ensure cross chains sit square to the road and hooks/fasteners face outward per the manufacturer.
5. Connect the chains: Fasten the inside connection first, then the outside. If your set has cams, snug them evenly with a cam tool. Follow the maker’s method in the Tire Chains Install Instructions.
6. Adjust the tension: Chains should be tight and centered with minimal slack. Use cams or, where appropriate, a heavy-duty adjuster (e.g., a large-truck spring tensioner).
7. Repeat for required tires: Install on the remaining tires per local rules and your fleet policy (often the outside tires of the drive axles; check your jurisdiction/conditions).
8. Check the fit: Confirm the chains are centered with even coverage across the tread. Re-seat any twisted cross chains and re-snug fasteners.
9. Inspect & test: Roll forward 50–100 feet and re-tighten as needed. Listen for slap or vibration and re-center. Re-inspect periodically during the route; remove chains when roads are clear.

Tip: For temporary traction emergencies, fleets sometimes carry ratchet strap-on emergency chains. Use only as directed and verify clearances before operation.
