Can You Put Chains on a Subaru

You can put chains on a Subaru, but not all models are compatible due to tight wheel well clearances and AWD system requirements. Always check your owner’s manual and use only approved chain types to avoid damage. For many Subarus, alternatives like snow socks or all-weather tires may be safer and more practical.

Key Takeaways

• Not all Subarus support tire chains: Models with limited wheel well space (like the Impreza or Crosstrek) often can’t safely accommodate traditional chains.
• Check your owner’s manual first: Subaru explicitly states whether your specific model allows chains—never assume.
• Cable chains are often the only approved option: These low-profile alternatives fit tighter spaces and reduce the risk of damaging suspension or body components.
• Improper installation can cause serious damage: Chains that rub against brake lines, CV joints, or fenders can lead to costly repairs.
• Snow socks are a lightweight alternative: These fabric covers slip over tires and provide traction without metal—ideal for tight-clearance Subarus.
• All-wheel drive isn’t a substitute for traction aids: Even with AWD, you may still need chains in deep snow or icy mountain passes.
• Practice installation before you need it: Putting on chains in a snowy, dark parking lot is much harder than doing it at home in good conditions.

Can You Put Chains on a Subaru? The Truth About Traction and Compatibility

If you live in a snowy region or plan to drive through mountain passes during winter, you’ve probably wondered: *Can you put chains on a Subaru?* After all, Subarus are known for their standard all-wheel drive (AWD), rugged design, and popularity among outdoor enthusiasts. But having AWD doesn’t automatically mean your Subaru is chain-ready.

The short answer is: **yes, you can put chains on some Subarus—but not all.** And even when you can, there are important rules, restrictions, and alternatives to consider. Installing chains incorrectly—or using the wrong type—can damage your vehicle, void your warranty, or even create a safety hazard.

In this guide, we’ll walk you through everything you need to know about using tire chains on your Subaru. From model-specific compatibility to installation tips and modern alternatives like snow socks, we’ll help you make the safest, smartest choice for winter driving.

Why Tire Chains Matter—Even in an AWD Subaru

You might think, “My Subaru has all-wheel drive—why would I need chains?” It’s a fair question. AWD helps with acceleration and stability on slippery roads by sending power to all four wheels. But here’s the catch: **AWD improves traction during acceleration, not braking or cornering.**

When roads are covered in ice or deep snow, your tires still need grip to stop, turn, and maintain control. That’s where tire chains come in. Chains bite into snow and ice, providing the extra traction that even the best AWD system can’t deliver on its own.

In many mountainous areas—especially in states like California, Colorado, and Washington—chain controls are mandatory during winter storms. Signs may say “Chains Required” or “Minimum Tread Depth 6/32”—and if you don’t comply, you could be fined or turned back.

So even if your Subaru handles well in light snow, chains (or an approved alternative) might be legally required—and essential for safety—in severe conditions.

When Are Chains Required?

Chain requirements vary by location and weather, but common scenarios include:

– Driving over mountain passes (e.g., Donner Pass in California, Snoqualmie Pass in Washington)
– Heavy snowfall or icy road conditions
– Chain control checkpoints enforced by highway patrol
– Steep, winding roads with poor visibility

Always check local road conditions before heading out. Apps like Caltrans QuickMap (for California) or WSDOT (Washington) provide real-time chain requirements and road closures.

Which Subaru Models Can Use Tire Chains?

Not every Subaru is built the same when it comes to tire chains. The main factor is **wheel well clearance**—the space between your tire and the suspension, brake lines, and inner fender.

Subarus with tighter packaging—especially compact models—often don’t have enough room for traditional metal chains. Here’s a breakdown by model:

Subaru Models That Typically Allow Chains

– **Subaru Outback:** One of the most chain-friendly Subarus. The larger wheel wells and higher ground clearance make it suitable for many chain types, including cable and link chains (with restrictions).
– **Subaru Forester:** Generally compatible with low-profile chains or cables, especially in newer models. Always check clearance with your specific tire size.
– **Subaru Ascent:** The three-row SUV has generous space, making it a good candidate for approved chains.

Subaru Models That Usually Don’t Allow Chains

– **Subaru Impreza:** Tight wheel wells and low profile tires often prevent safe chain use. Most Imprezas are not chain-compatible.
– **Subaru Crosstrek:** Despite its rugged look, the Crosstrek has limited clearance. Subaru often states that chains are not recommended.
– **Subaru WRX/STI:** Performance models with aggressive suspension and low-profile tires are generally not chain-compatible.
– **Subaru BRZ:** Rear-wheel drive and tight packaging make chains impractical and potentially damaging.

How to Check Your Specific Model

The only way to know for sure is to **consult your owner’s manual**. Look for a section titled “Tire Chains” or “Winter Driving.” Subaru will explicitly state whether chains are allowed and, if so, what type is approved.

For example, the 2023 Subaru Outback manual says:
> “Tire chains can be used on your vehicle. However, use only cable chains or SAE Class “S” link-type chains.”

Meanwhile, the 2023 Crosstrek manual states:
> “Tire chains cannot be used on your vehicle due to insufficient clearance.”

Never rely on assumptions or online forums—your manual is the final authority.

Types of Tire Chains: What Works on a Subaru?

If your Subaru allows chains, you’ll still need to choose the right type. Not all chains are created equal—and using the wrong kind can damage your vehicle.

Cable Chains (Recommended for Most Subarus)

Cable chains are made of steel cables wrapped in polymer-coated links. They’re lighter, thinner, and more flexible than traditional link chains.

**Pros:**
– Low profile—fits tight spaces
– Less likely to damage suspension or body
– Quieter and smoother ride
– Often the only type approved by Subaru

**Cons:**
– Less durable than metal link chains
– May not provide as much grip in deep snow

Cable chains are ideal for Subarus with limited clearance. Brands like **Security Chain Company (SCC) Super Z** or **Laclede Cable Chains** are popular and Subaru-approved.

Link Chains (Use with Caution)

Traditional metal link chains offer maximum traction but are bulky and heavy. They’re best for heavy-duty use in deep snow.

**Pros:**
– Excellent grip on ice and deep snow
– Durable and long-lasting

**Cons:**
– Require more clearance
– Can damage paint, suspension, or brake lines if improperly installed
– Noisy and harsh ride

Only use link chains if your Subaru manual explicitly allows them—and only SAE Class “S” chains, which are designed for tight-clearance vehicles.

SAE Class “S” Chains: The Safe Choice

SAE (Society of Automotive Engineers) classifies chains by clearance requirements:

– **Class S:** For vehicles with limited wheel well space. Low-profile design.
– **Class U:** For vehicles with more clearance. Bulkier chains.

Always choose **Class S** chains for Subarus—even if your model allows chains. These are engineered to minimize interference with suspension components.

How to Safely Install Chains on Your Subaru

Putting on chains isn’t just about slapping them on and driving. Proper installation is critical for safety and to avoid damage.

Step-by-Step Installation Guide

1. **Park Safely:** Pull over on a flat, stable surface away from traffic. Turn on hazard lights.
2. **Lay Out Chains:** Unpack and unfold chains. Make sure they’re not twisted.
3. **Position the Vehicle:** If possible, drive forward slightly so the chains can be draped over the top of the tire.
4. **Drape Chains Over Tire:** Place the chain over the top of the tire, ensuring it’s centered.
5. **Connect the Inner Side:** Hook the inner side first (closest to the vehicle).
6. **Connect the Outer Side:** Pull the outer side tight and secure with fasteners or cam tighteners.
7. **Tighten and Adjust:** Drive forward 10–20 feet, then stop and re-tighten. Chains loosen after initial use.
8. **Check Clearance:** Ensure chains aren’t rubbing against brake lines, suspension, or fenders.

Tips for Easier Installation

– **Practice at home:** Install chains in your driveway before winter hits. It’s much harder in the cold and dark.
– **Use gloves:** Chains are cold, sharp, and dirty.
– **Carry a tarp or mat:** Keeps you dry while kneeling in snow.
– **Use tensioners:** Cam-style or rubber tighteners help keep chains snug.

What to Avoid

– **Don’t over-tighten:** This can damage the chain or tire.
– **Don’t drive fast:** Limit speed to 30 mph or less when using chains.
– **Don’t use on bare pavement:** Remove chains as soon as you reach clear roads to prevent damage.
– **Don’t ignore rubbing sounds:** If you hear scraping, stop immediately and check for interference.

Alternatives to Tire Chains for Subaru Owners

If your Subaru doesn’t allow chains—or you want a lighter, easier option—consider these modern alternatives.

Snow Socks

Snow socks are fabric covers that slip over your tires like a sleeve. Made from high-friction textile, they provide excellent grip on snow and ice.

**Pros:**
– Ultra-lightweight and compact
– Easy to install—no tools needed
– Quiet and smooth ride
– Safe for tight-clearance vehicles

**Cons:**
– Not effective on bare ice
– Limited lifespan (typically 1–2 seasons)
– Not legal in all states (check local laws)

Snow socks are ideal for short trips or emergency use. Brands like **Sno-Shoe** and **Tire Socks** are popular.

All-Weather and Winter Tires

The best long-term solution for winter driving is the right tire.

– **All-Weather Tires:** Rated with the 3PMSF (Three-Peak Mountain Snowflake) symbol. Designed for year-round use with good snow performance.
– **Winter Tires:** Made from softer rubber that stays flexible in cold temps. Best for severe snow and ice.

Even with AWD, winter tires dramatically improve braking, cornering, and acceleration in cold conditions.

Automatic Traction Systems

Some newer vehicles offer automatic traction aids like:

– **Spiked Tire Inserts:** Small metal studs that deploy when needed (not common on Subarus).
– **On-Demand Traction Mats:** Portable mats you place under tires for extra grip (e.g., Maxtrax).

These aren’t replacements for chains but can help in emergencies.

Common Mistakes to Avoid When Using Chains on a Subaru

Even experienced drivers make errors with tire chains. Here’s what to watch out for:

Assuming All Subarus Are Chain-Compatible

Just because your friend put chains on their Outback doesn’t mean you can do the same on your Crosstrek. Always check your manual.

Using the Wrong Chain Type

Installing heavy link chains on a vehicle designed only for cables can crack fenders or damage CV joints.

Not Practicing Installation

Fumbling with chains in a snowstorm at night is stressful and dangerous. Practice at home.

Forgetting to Remove Chains

Driving on dry pavement with chains wears them out quickly and can damage your tires and drivetrain.

Ignoring Speed Limits

Most chains are rated for 30 mph or less. Exceeding this can cause failure or loss of control.

Final Thoughts: Making the Right Choice for Your Subaru

So, can you put chains on a Subaru? The answer depends on your model, your driving needs, and the conditions you face.

If your Subaru allows chains—and you frequently drive in chain-controlled zones—invest in a quality set of **cable chains or SAE Class “S” link chains**. Practice installation, follow the manual, and always drive cautiously.

If your Subaru doesn’t allow chains, don’t panic. **Snow socks, winter tires, and careful driving** can get you through most winter conditions safely. And remember: AWD helps, but it’s no substitute for proper traction aids in extreme weather.

Ultimately, the best approach is preparation. Check your owner’s manual, equip your Subaru appropriately, and stay informed about road conditions. With the right tools and knowledge, you can drive confidently—no matter how much snow falls.
