Difficulty: EasyWinter Driving

When preparing for severe winter road conditions where chain controls are active, a commercial driver must properly install tire traction chains on the drive wheels. What is the correct chronological sequence of steps for safely mounting and securing tire chains on a drive tire?

  1. 1Lay the tire chains flat on the ground to untangle cross-links and ensure the hooks face in the proper direction.
  2. 2Drape the chain evenly over the top of the drive tire with the open ends of the cross-chain hooks facing outward away from the tire rubber.
  3. 3Roll the vehicle forward a partial turn of the wheel so the tire rolls onto the draped cross-chains.
  4. 4Fasten the inner side rail hook first, connect the outer side rail fastener, and secure all slack with tensioners.

Answer

Lay the chains flat to remove tangles, drape the chain over the drive tire with hook ends facing outward, roll the vehicle forward onto the chain, and fasten the inner rail before the outer rail and tensioners.
The proper sequence starts by laying out and untangling the chains, draping them over the tire with hooks pointed away from the casing, rolling forward a partial wheel turn to position the ends, and connecting the inside fastener before the outside fastener and tensioners.

Step-by-Step Solution

1
Unfold and lay chains flat on the ground beside the drive wheel.
Any twists, kinks, or inverted cross-hooks are identified and straightened before mounting.
Chains cannot be fitted evenly or safely if links are twisted or tangled.
2
Place the chain evenly over the top of the tire with open hook ends pointing away from the tire.
The chain covers the upper half of the tread while protecting the tire casing from puncture or abrasive damage.
Hooks pointing toward the tire can dig into the sidewall or tread under load.
3
Drive the vehicle slowly forward approximately one-quarter to one-half wheel rotation.
The tire sits on top of the cross-chains, exposing both open ends of the side rails.
Rolling forward positions the loose ends where they can easily reach each other for latching.
4
Hook the inside rail link first, latch the outside rail fastener, and apply rubber tighteners.
The chain is centered across the tread face and held under uniform tension.
Securing the inner hook first prevents the chain from sliding off toward the outside during final tightening.
