Snow chains can dramatically improve traction on snow and ice, but only when they’re installed on the correct tires, fitted tightly, and used at the right speed. This guide walks you through choosing the right chain type, installing it safely, and driving without damaging your vehicle or the road.

Before you start: confirm you actually need chains

  • Check local rules and signage: Some mountain passes and winter roads require chains during storms, while other areas restrict them to certain conditions.
  • Know your vehicle limitations: Some cars (especially low-clearance vehicles) may have limited space around the tire. Your owner’s manual may specify chain compatibility or recommend cable-style chains instead.
  • Chains aren’t for bare pavement: Using chains on clear roads can reduce handling, increase stopping distance, and damage chains, tires, and road surfaces.

What you need

  • Snow chains sized for your exact tire size (e.g., 225/55R17)
  • Gloves (waterproof/insulated if possible)
  • Kneeling pad or small tarp (optional, but helpful)
  • Headlamp/flashlight
  • Tensioners (if not built-in) and the included instructions

Step 1: Choose the right chains for your tires and drivetrain

Start with your tire sidewall size and buy chains that explicitly match it. If you drive:

  • Front-wheel drive (FWD): Install on the front tires.
  • Rear-wheel drive (RWD): Install on the rear tires.
  • All-wheel drive / 4WD: Many jurisdictions still accept chains on one axle, but for best stability follow your owner’s manual. Some vehicles specify a particular axle or chain type.

Tip: If your car has tight clearance, look for low-profile chains or cables approved for your vehicle. Forcing bulky chains into a tight wheel well can damage brake lines, suspension components, or bodywork.

Step 2: Practice at home (seriously)

The worst time to learn is on the shoulder in a blizzard. Do a dry run in your driveway:

  • Unpack chains and identify the inside/outside and the fasteners.
  • Do one full install and removal so you know the sequence.
  • Check that nothing rubs when the wheel turns (if you can safely move the car slightly).

Step 3: Pull over safely before conditions get too bad

  • Choose a flat area away from traffic if possible (chain-up areas are ideal).
  • Turn on hazard lights.
  • Set the parking brake and put the car in Park (or in gear for manual transmissions).
  • Place warning triangles if you carry them and it’s safe to do so.

Step 4: Lay out and untangle the chains

Lay each chain flat on the ground and remove twists. A twisted chain won’t tension correctly and can slap the wheel well.

  • Position the chains so the fastening points are accessible from outside the tire.
  • Make sure any hooks meant to face outward do so (to reduce the chance of damaging the tire sidewall).

Step 5: Install the chains on the correct wheels

Installation style varies (traditional link chains vs. cable chains vs. “easy-fit” systems), but the core ideas are the same:

  1. Drape or position the chain: Center it over the top of the tire or behind it (depending on design).
  2. Connect the inside fastener first: This is usually the most awkward step—do it before your hands get too cold.
  3. Connect the outside fastener: Keep the chain centered on the tread.
  4. Add tensioners if required: These help keep the chain snug and reduce flailing.

Goal: The chain should sit evenly across the tread with minimal slack.

Step 6: Roll forward and re-tighten

After both sides are installed (or after completing one axle):

  • Drive forward about 30–100 feet (10–30 meters) slowly.
  • Pull over again and re-check tension.
  • Tighten any loosened connectors and re-center the chain if it shifted.

This step matters: chains often “seat” into place after the tire rotates.

Step 7: Drive with chains the right way

  • Respect speed limits for chains: Many manufacturers recommend staying at or below 30 mph (50 km/h). Always follow the chain’s instructions and any posted limits.
  • Avoid sudden inputs: Gentle acceleration, gradual steering, and longer braking distances reduce skidding and chain stress.
  • Listen for problems: Loud banging, repeated slapping, or vibration can mean a loose chain or incorrect fit—stop and fix it.
  • Don’t spin the tires: Wheelspin can break chains and whip them into your fender or brake components.

Step 8: Remove chains as soon as you’re back on clear pavement

Once roads are mostly bare, pull off safely and remove them:

  1. Unhook outside fasteners and tensioners.
  2. Unhook inside fasteners.
  3. Lay chains out, then roll the vehicle off them if your chain style requires it (or pull them free if they’re draped type).
  4. Dry and repack them to prevent rust and tangles later.

Common mistakes to avoid

  • Buying the wrong size: “Close enough” isn’t close enough—chains must match your tire size exactly.
  • Installing on the wrong axle: This reduces control and can increase the risk of sliding.
  • Skipping the re-tighten step: Loose chains can break and damage the vehicle.
  • Driving too fast: Higher speeds increase heat, wear, and the chance of chain failure.
  • Using chains where they’re not needed: Bare pavement quickly destroys chains and harms handling.

Quick safety checklist

  • Chains match tire size and vehicle clearance
  • Installed on correct axle (or per owner’s manual)
  • Evenly centered, minimal slack
  • Re-tightened after a short drive
  • Speed kept within chain/manufacturer limit
  • Removed once roads clear

If you treat snow chains like emergency equipment—practice ahead of time, install early, and drive conservatively—they can be the difference between getting home safely and getting stuck (or worse) in dangerous winter conditions.
