• Vehicle Requirements: The Colorado chain law​ applies to all commercial vehicles with a Gross Vehicle Weight Rating (GVWR) of 26,001 pounds or more.
• Chain-Up Stations: The Colorado Department of Transportation (CDOT) has designated chain-up and chain-down stations along I-70. These are the only places where it is safe and legal to install or remove your chains. Stopping in a live lane of traffic to put on chains will result in a major fine.

How to Install Tire Chains on a Truck (I-70 Colorado chain law​ Compliant)

What You’ll Need:

• Tire chains (appropriate size for your truck’s tires)
• Gloves (to protect your hands from cold and sharp edges)
• Flashlight (if visibility is low)
• A safe, flat area (preferably a designated chain-up station)

---

Step-by-Step Installation Process:

1. Park Safely:

•  Pull over at a designated chain-up station along I-70. Avoid stopping in a live traffic lane, as this is both dangerous and illegal.

2. Lay Out the Chains:

•  Unroll the chains and lay them flat on the ground. Ensure there are no twists or tangles.
• Position the chains so the hooks face outward (away from the tire) to prevent damage to the tire sidewall.

3. Position the Chains:

• Drape the chains over the top of the tire, ensuring they are evenly distributed. The chains should cover the tire tread and hang down the sides.

4. Connect the Chains:

• Start by fastening the inside hooks or clips first, then move to the outside. This ensures the chains are secure and won’t slip off.
• Tighten the chains as much as possible to prevent them from loosening during travel.

5. Drive Forward Slightly:

• Move the truck forward a few feet to expose the part of the tire that was on the ground. Adjust and secure the chains to ensure full coverage.

6. Tighten Again:

• Use a chain tensioner or bungee cords to keep the chains snug against the tire. Loose chains can cause damage or fall off while driving.

7. Test the Chains:

• Drive a short distance (at low speed) to ensure the chains are properly installed and not making excessive noise or causing vibrations.

Drivers should also carry essential car components and tools to handle breakdowns or roadside emergencies during winter

Pro Tips for Easy Installation:

• Practice Before Winter: Familiarize yourself with the process in good weather to avoid stress during a storm.
• Carry Extras: Keep spare chains and tensioners in case of breakage. And don’t forget—if your truck is consistently struggling to pull grades, it may be time for a dependable Ford F-250 Super Duty engine or 6R140 transmission

• Check Fit: Ensure the chains are the correct size for your tires before heading out.
• Stay Updated: Monitor CDOT road conditions for Colorado chain law​ enforcement updates.

---

When to Remove Chains:

• Only remove chains at designated chain-down stations once you’ve cleared the hazardous area. Driving on bare pavement with chains can damage both the chains and your tires.

Always monitor weather conditions closely before embarking on the I-70 drive—and make sure your truck is mechanically prepared. Whether it’s an engine upgrade or a transmission replacement, proper prep can make the difference between a smooth haul and a roadside breakdown.
