As someone who’s spent over a decade exploring the backcountry and guiding trips across the American West, I can tell you that winter driving presents unique challenges. One of the most crucial pieces of equipment for safe travel in snowy or icy conditions is a set of security chain snow chains. Knowing how to choose the right chains, properly install them, and understand the max speed with snow cables is paramount for a successful and, more importantly, safe winter adventure. This guide will cover everything you need to know, from legal requirements to practical tips, ensuring you’re prepared for whatever Mother Nature throws your way.
Understanding the Need for Snow Chains
Many states and even specific roadways within states (especially in mountainous regions) require or recommend the use of snow chains during certain winter conditions. These requirements are often triggered by snowfall levels or road conditions, and ignoring them can result in fines or, worse, a dangerous situation. The National Park Service provides excellent resources on chain requirements for parks across the country. But beyond legal mandates, security chain snow chains dramatically improve traction on snow and ice, providing significantly better control than even winter tires in severe conditions. They work by biting into the snow and ice, creating friction that allows you to accelerate, brake, and steer more effectively.
Types of Snow Chains: Cables vs. Chains
It’s important to understand the difference between snow cables and traditional snow chains. Both are designed to improve traction, but they differ in construction and application:
- Snow Chains (Traditional Chains): These are typically made of hardened steel links and offer the most aggressive grip. They are ideal for deep snow, thick ice, and steep inclines. However, they can be noisier and provide a rougher ride.
- Snow Cables (Cable Chains): These use steel cables with cross chains attached. They are generally easier to install, quieter, and provide a smoother ride than traditional chains. They are best suited for moderate snow and ice conditions.
Choosing between the two depends on your typical driving conditions and vehicle type. For most passenger vehicles and light trucks encountering moderate winter conditions, snow cables are often sufficient. However, if you frequently drive in deep snow or on steep, icy roads, traditional chains are the better choice. REI’s Expert Advice section offers a detailed comparison of the two.
Choosing the Right Snow Chains for Your Vehicle
Selecting the correct security chain snow chains is critical. Using the wrong size can damage your vehicle or render the chains ineffective. Here’s what you need to consider:
- Tire Size: This is the most important factor. Check your tire sidewall for the tire size (e.g., 225/65R17). Snow chain manufacturers provide sizing charts based on tire size.
- Vehicle Type: Different vehicles require different chain types. Some vehicles with limited wheel well clearance may require “low-profile” chains.
- Drive Type:
- Front-Wheel Drive (FWD): Chains are typically installed on the front tires.
- Rear-Wheel Drive (RWD): Chains are typically installed on the rear tires.
- All-Wheel Drive (AWD) / Four-Wheel Drive (4WD): The manufacturer’s recommendation varies. Some recommend chains on all four tires, while others suggest chains on the front or rear depending on the vehicle’s system. Always consult your vehicle’s owner’s manual.
Many retailers offer online tools to help you find the correct chains for your vehicle. Don't hesitate to ask a knowledgeable salesperson for assistance.
Installation: A Step-by-Step Guide
Proper installation is crucial for the security chain snow chains to function effectively and prevent damage to your vehicle. I always recommend practicing installation before you need them in a blizzard. Here’s a general guide (always refer to the manufacturer’s instructions for your specific chains):
- Safety First: Park on a level surface away from traffic. Engage the parking brake.
- Lay Out the Chains: Spread the chains out and ensure they are not tangled.
- Position the Chains: Drape the chains over the tire, ensuring the chains are evenly distributed.
- Connect the Inner Chain: Connect the inner chain around the tire.
- Secure the Outer Chain: Connect the outer chain and tighten the chains using the provided tightening mechanisms.
- Test and Adjust: Drive a short distance (a few feet) and re-check the chains to ensure they are secure and properly positioned.
The YouTube is full of helpful videos demonstrating proper installation techniques.
Understanding Max Speed with Snow Cables and Chains
This is where many drivers make mistakes. Knowing the max speed with snow cables and chains is vital for safety and preventing damage. Generally:
- Snow Cables: The max speed with snow cables is typically 30 mph (48 km/h).
- Traditional Snow Chains: The max speed with snow chains is typically 25 mph (40 km/h).
These are maximum speeds, and you should adjust your speed based on road conditions. Driving too fast with chains or cables can cause them to break, damage your vehicle, or lose control. Avoid sudden acceleration, braking, and turning. The USDA Forest Service (fs.usda.gov) emphasizes the importance of slow and steady driving in winter conditions.
Signs You're Going Too Fast
Pay attention to these warning signs:
- Excessive Vibration: If you feel significant vibration in the steering wheel or vehicle, you’re likely going too fast.
- Chain Noise: Increased chain noise indicates the chains are working too hard and may be nearing their limit.
- Loss of Control: Any feeling of instability or loss of control is a clear sign to slow down.
Maintenance and Storage
Proper maintenance and storage will extend the life of your security chain snow chains.
- After Each Use: Remove the chains and clean them with a brush and mild detergent. Dry them thoroughly to prevent rust.
- Lubrication: Lightly lubricate the chains with a rust inhibitor.
- Storage: Store the chains in a dry, protected location. Avoid storing them directly on the floor, as this can cause them to rust.
Legal Considerations and Road Closures
Always check current road conditions and chain requirements before traveling. State Departments of Transportation (DOTs) websites provide real-time information on road closures and chain restrictions. Ignoring chain requirements can result in fines and delays. Be aware that even with chains, some roads may be closed due to extreme weather conditions. The Federal Highway Administration provides resources on winter road maintenance and safety.
Beyond Chains: Winter Driving Preparedness
While security chain snow chains are essential, they are just one part of winter driving preparedness. Here’s a checklist:
- Winter Tires: Consider using winter tires for optimal traction.
- Emergency Kit: Carry a winter emergency kit with blankets, food, water, a flashlight, a first-aid kit, and a shovel.
- Full Tank of Gas: Keep your gas tank full to avoid running out of fuel in remote areas.
- Charged Cell Phone: Ensure your cell phone is fully charged.
- Inform Someone of Your Plans: Let someone know your travel route and estimated arrival time.
I’ve seen firsthand how quickly conditions can change in the mountains. Being prepared can make all the difference between a safe journey and a dangerous situation. Remember, prioritizing safety is always the most important thing. For more in-depth information on winter travel planning, check out my article on Winter Backcountry Travel Planning.
