2020 Subaru WRX Winter Tire Guide: Maximize Snow Performance

Summary

The most common and effective solution for inadequate snow traction is to install a dedicated set of winter tires, with studded tires being the top recommendation for severe ice conditions. Based on 16 owner discussions, the consensus is that all-season or summer "sport" tires are insufficient for true winter driving, especially in mountainous regions or areas with persistent ice.

Signs to Watch For

Owners reporting "snow tire problems" typically describe a dangerous lack of control and traction in winter conditions. Key signs include:

• Uncontrolled sliding or spinning: The vehicle loses traction when accelerating from a stop or on inclines, even with careful throttle input.
• Inability to stop: Significantly increased braking distances on snow and ice, often described as "sliding through intersections."
• Poor handling on packed snow or ice: The vehicle feels unstable, "floaty," or drifts during cornering on snow-covered roads.
• Getting stuck frequently: Needing assistance or being unable to navigate unplowed streets or driveways that other vehicles manage.
• A specific mention of "mountain driving": Many discussions highlight that the problem becomes critically dangerous on mountain passes or steep, icy grades.

Fast Fix

The immediate and most reliable fix is to mount a set of four dedicated winter tires. For drivers facing severe, persistent ice (common in mountain regions or certain northern climates), studded winter tires are frequently cited as the definitive solution for regaining control and stopping power.

How to Fix It

Solutions are ranked by their frequency of mention and reported success in owner discussions.

1. Install Four Dedicated Winter Tires (Most Common Solution)

This was the unanimous recommendation across all discussions. Winter tires use a softer rubber compound that stays pliable in cold temperatures and features aggressive tread patterns designed to bite into snow and evacuate slush.

• Success Rate: Universally reported as a transformative improvement.
• Note: Owners stress that installing only two winter tires can create a dangerous imbalance in handling. Always install a complete set of four.

2. Upgrade to Studded Winter Tires for Extreme Ice

For the most challenging conditions—specifically, hard-packed ice and "glare ice" common on mountain roads—many experienced owners recommend studded tires.

• How They Work: Metal studs embedded in the tread provide mechanical grip on sheer ice.
• Consideration: Check local regulations, as stud use is restricted or prohibited in some areas and seasons due to road wear. They may also be noisier on dry pavement.

3. Use Tire Chains or AutoSocks for Emergency/Legal Compliance

When caught without adequate tires or when legally required (e.g., posted chain control areas in mountains), traction devices are a mandatory backup.

• Chains: Provide maximum bite but must be installed and driven at low speeds (typically under 30 mph).
• AutoSocks: A textile alternative that is often easier to install and is approved in some chain-control areas. They are for temporary, low-speed use.
• Important: These are not a substitute for proper winter tires for general driving.

4. Verify Tire Type and Condition (Diagnostic Step)

Before any purchase, confirm you are not already using winter tires. The problem may be caused by:

• Worn-Out Tires: Any tire, including a winter model, is dangerous if the tread depth is below 4/32".
• Using "Sport" or Summer Tires: These tires harden like hockey pucks in freezing temperatures and offer virtually no snow or ice traction. Switching from these to winter tires yields the most dramatic improvement.

What Owners Paid

Costs vary widely based on vehicle tire size, tire brand, and installation choice.

• Dedicated Winter Tires (Set of 4):

  • Parts (Tires Only): $400 - $1,000+. Premium brands (e.g., Nokian, Blizzak, Michelin X-Ice) are at the higher end.
  • DIY on Separate Wheels: If you purchase a second set of inexpensive steel wheels ($200-$400), you can mount and balance the tires once and swap them yourself each season, saving on recurring labor.
  • Shop Labor (Seasonal Swap): $50 - $100 per season for mount/balance if using the same wheels.

• Studded Winter Tires:

  • Parts: Typically $50 - $150 more per tire than non-studded equivalents.
  • Labor: An additional $15 - $25 per tire for the stud installation service.

• Professional Recommendation: Investing in a second set of wheels for your winter tires is the most cost-effective and convenient long-term strategy. It prevents twice-yearly mounting/balancing fees and reduces the risk of wheel damage from seasonal changes.

Keeping It From Happening

Prevent being caught without proper traction by planning ahead.

1. Mount Tires Early: Install winter tires when consistent temperatures are at or below 45°F (7°C). Don't wait for the first snowstorm.
2. Use a Two-Set System: Maintain a dedicated set of winter tires on their own wheels and a set of summer/all-season tires. Swap them seasonally.
3. Store Tires Properly: Keep off-season tires in a cool, dry, dark place away from ozone sources. Stack them horizontally or hang them—do not store them mounted under vehicle weight.
4. Know the Law: Research chain control laws and studded tire regulations for any mountain passes or regions you plan to drive through in winter.
5. Check Tread Annually: Use a tread depth gauge. Replace winter tires before they reach 4/32" of remaining tread for safe snow performance.
