New Tires in Washington (WA)

Washington is a state, often referred to as Washington state, to distinguish it from the national capital. It is located in the Pacific Northwest region of the United States. Both the capital and state were named after the first U.S. President and Founding Father, George Washington. This is the 18th-largest state and the 13th most populous.

Also known as the “Evergreen State,” Washington is uniquely defined by its dramatic contrast between lush western temperate rainforests and arid eastern landscapes. It is also the top producer of apples, cherries, and hops, and is the home of tech giants like Amazon and Microsoft.

Washington State is home to five major volcanoes: Mt. Adams, Mt. Baker, Glacier Peak, Mt. Rainier, and Mt. St. Helens. One of the largest volcanic eruptions in North America was Mt. St. Helens in 1980.

Tires Based On The Weather

Washington State has a diverse climate. The weather is defined by a wet, temperate oceanic climate west of the Cascade Mountains with mild summers and winters, and a semi-arid continental climate to the east, with hot summers and cold winters. The statewide temperatures average around 47°F, with Western Washington winters seeing highs in the 40s°F range, while Eastern Washington summers can exceed 90s°F.

Because of this, all season tires are generally a good choice for most drivers. However, all season tires are designed to handle mild climates, and cannot handle moderate to severe winter conditions. When temperatures drop and stay below 47°F, you should switch to winter-dedicated tires, especially if there’s ice and snow on the roads. All weather tires are also a great choice, as they perform better in winter conditions compared to all season tires.

The all weather tires are becoming increasingly more popular in the Pacific Northwest.

A good alternative is the Pirelli Cinturato WeatherActive, which offers exceptional year-round traction.

Best All Season Tires For Washington

These tire types often provide a long tread life and excellent hydroplaning resistance, with mild winter performance. The Michelin Defender 2 is a popular all season choice, featuring an optimal tread design that helps with hydroplaning, offering better grip in heavy rain. Another great choice is the Continental ExtremeContact DWS 06 Plus, perfect for those who drive sports sedans or SUVs.

Best Summer Tires For Washington

While most Washington state drivers stick to all season or all weather tires due to the frequent “winter-to-spring” swings, Summer tires are a popular choice among performance enthusiasts and luxury commuters. These tires are known not only for their performance in high heat but also in rainy weather. Continental SportContact 7 tires are the highest-rated for offering a balanced performance, while the Michelin Pilot Sport 5 is the gold standard for sports cars.

Michelin X-Ice Snow is known for its “Flex-Ice 2.0” compound, which remains flexible in extreme cold in Eastern Washington. The Bridgestone Blizzak WS90 is also a popular choice, designed to be used on icy mountain passes.

Most Popular Tire Sizes In Washington

Washington State has many Subaru Outbacks, Toyota RAV4s, and Ford F-150s, so the tire sizes are heavily skewed toward crossovers, SUVs, and light trucks. The most popular sizes generally fall into categories based on Washington’s most common vehicle types:

225/60R18

A very common size for modern crossovers, such as Subaru Outback and Subaru Forester, Honda CR-V, BMW X3, and others.

225/65R17

This is the most widely available size in the state. It is commonly seen on the Toyota RAV4, Honda CR-V, and Subaru Outback.

265/70R17

This is usually the go-to size for light trucks. In Washington, you’ll almost always see these equipped on all terrain tires on vehicles like the Ford F-150, Chevrolet Silverado, and Ram 1500.

Washington Driving Laws You Need To Know

Washington state road laws balance accessibility with safety, featuring moderate speed limits, comprehensive safety requirements, and protections designed for the state’s diverse terrain, from coastal regions to mountain passes and variable Pacific Northwest weather conditions.

Studded Tire Season

Washington has a very strict window when studded tires can be used, from November 1 to March 31. If used after this period, you will be fined, and there are no individual exceptions for mountain residents.

Mountain Pass Chain Requirements

Even if it’s a sunny day, all vehicles over 10,000 lbs (including large SUVs) must carry chains when crossing mountain passes.

The “Single Touch” Rule

Holding a phone for any reason, even at a stopped light, will result in a fine. You are only allowed a minimal “use of a finger” to activate or deactivate a function, like answering a call or starting GPS, while the phone is in a cradle or mounted.

Headlights

In Washington’s “Big Dark” (the rainy season), the law requires headlights to be on whenever you are using your windshield wipers. This is a primary safety focus for the State Patrol during the misty winter months.

The "Emergency Zone" Move Over Law

This is one of the strictest laws in the West. If you see any stationary vehicle with flashing lights (police, tow trucks, or even a stranded motorist with hazard lights), you must move over one lane. If you cannot move over safely, you must slow down to at least 10 MPH below the posted speed limit.

When To Change Your Tires In Washington

While all season tires are a great option in most Washington areas, they are not suitable for sustained cold temperatures or severe winter weather conditions. If you live in regions where temperatures consistently stay below 45°F, and roads are frequently covered with ice and snow, such as the Cascades or eastern Washington, you need dedicated winter tires for optimal safety and control.

You could also choose all weather tires as a year-round solution. These tires carry the 3PMSF certification, meaning they meet harsh snow traction standards and perform well in moderate winter conditions. This eliminates the need for seasonal tire swaps while still providing adequate winter performance for most Washington drivers, including those who occasionally travel mountain passes.

Frequently Asked Questions

Are Studded Tires Legal In Washington?

Yes, studded tires are legal in Washington from November 1 to March 31. Outside of this period, they are prohibited on paved roads. Washington State Patrol recommends studless winter tires with the 3PMSF symbol as a quieter, pavement-friendly alternative that performs well in winter conditions.

What Is The 3PMSF Symbol, And Why Does It Matter In Washington?

The 3PMSF (Three-Peak Mountain Snowflake) symbol certifies that a tire meets specific severe snow traction performance requirements. In Washington, tires with this symbol satisfy “Traction Tires Required” signs on mountain passes, making them essential for pass travel from November through March.

Are All Weather Tires A Good Choice For Washington Drivers?

Yes, all weather tires are increasingly popular in Washington because they carry the 3PMSF certification and handle the state’s diverse conditions well. Although they eliminate the need for seasonal tire changes, keep in mind that they cannot outperform winter tires in winter conditions.
