Tire Buying Guide: All-Season vs All-Weather vs Winter Tires

Picking the right tires for Pacific Northwest driving isn't as simple as it sounds. Our weather doesn't fit neatly into any single tire category — we get constant rain, occasional snow at lower elevations, serious snow at the passes, and stretches of dry summer roads. The best tires for Pacific Northwest conditions depend on how you drive, where you go, and how much you want to spend.

Our service department in Bellingham mounts and balances tires for drivers across Whatcom County, and this is one of the questions we hear most. Here's our honest breakdown.

Understanding the Three Categories

All-Season Tires
All-season tires are the default option on most new vehicles. They handle dry roads well, perform reasonably in rain, and can manage light snow — but "all-season" is a marketing term, not a performance promise.

What all-seasons don't do well: deep snow, ice, and sustained cold temperatures. The rubber compound in most all-season tires stiffens as temperatures drop toward the mid-40s °F, reducing grip. For most in-town Bellingham driving, all-seasons are adequate — but only just.

All-Weather Tires
This is the category that makes the most sense for most PNW drivers. All-weather tires carry the Three-Peak Mountain Snowflake (3PMSF) symbol, meaning they've passed a standardized severe-snow traction test — most all-seasons don't carry that rating.

They perform like a good all-season in summer and fall but use a rubber compound that stays pliable in the cold, closer to a winter tire. You don't need to swap them out seasonally.

Winter/Snow Tires
Dedicated winter tires are the best option for anyone who regularly drives over Snoqualmie Pass, Stevens Pass, or up the Mount Baker Highway. They offer dramatically better grip in deep snow and on ice, thanks to aggressive tread patterns and specialized rubber compounds.

The downside: they wear quickly in warm weather and need to be swapped on and off seasonally — which means either owning a second set of wheels or paying for mounting and balancing twice a year.

Tread Depth: When Do You Actually Need New Tires?

Here's a quick guide:

• New tire: roughly 10/32" tread depth (varies by tire)
• Replace for wet and winter conditions: at or below 4/32"
• Legal minimum in Washington: 2/32" (but honestly, don't wait that long)
• The penny test: Insert a penny upside down into the tread. If you can see the top of Lincoln's head, you're at 2/32" and need tires now.
• The quarter test: Use a quarter the same way. If you can see the top of Washington's head, you're at about 4/32" — start shopping.

Brands Worth Looking At

For all-weather tires (our top recommendation for most local drivers):

• Michelin CrossClimate2 — Excellent wet traction and 3PMSF rated.
• Nokian Remedy WRG5 — From a Nordic brand that knows winter; built for year-round use.
• Bridgestone WeatherPeak — Comfortable, quiet, and 3PMSF rated.

For dedicated winter tires (if you regularly drive mountain passes):

• Bridgestone Blizzak WS90 — A long-time favorite for ice and packed snow.
• Michelin X-Ice Snow — Strong winter grip with good tread life.
• Cooper Evolution Winter</
