What tires come on a Subaru Ascent?

The Subaru Ascent does not have a single tire configuration. OEM tires vary by model year and trim; base models commonly use 18-inch wheels with 245/60R18 tires, while higher trims use 20-inch wheels with around 255/45R20 tires. For the exact specification on your vehicle, check the tire placard in the driver’s door jamb or the owner’s manual.

Tire sizes by trim and year

Common configurations across recent years

The following outlines typical factory tire sizes used on the Ascent by trim level. Exact sizes can vary by year and market, so always verify your specific vehicle’s spec.

• Base and Premium trims (18-inch wheels): 245/60R18 all-season tires.


• Limited and Premier trims (20-inch wheels): 255/45R20 all-season tires.

These sizes cover most late-model Ascent configurations, but some markets or special editions may use alternative sizes. Always confirm the exact specification on the placard affixed to the door frame.

What to know when replacing tires

When selecting replacements for a Subaru Ascent, keep these guidelines in mind to maintain safety and performance.

• Match the original size and rating (size, load index, and speed rating) to preserve handling and safety systems.


• Install tires in a way that keeps the same size on all four corners; mixing sizes across axles can affect traction control and ABS behavior.


• Consider the climate and intended use: all-season tires are common, but dedicated winter tires are recommended in snowy regions.


• Ensure proper mounting, balancing, and alignment; consult a professional if you’re unsure.

Sticking to the factory specifications is the safest path. If you’re unsure about the correct size or rating for your exact model year, consult the owner’s manual or your local Subaru dealer for confirmation.

Additional considerations

Beyond size, some Ascent owners may encounter optional tire packages or run-flat configurations on certain trims or markets. Confirm whether your vehicle came with a standard or alternative setup, especially if shopping for used tires or replacements from a different market.

Summary

In most recent Subaru Ascent models, the factory tire size comes in two primary configurations: 18-inch wheels with 245/60R18 for base/Premium trims, and 20-inch wheels with 255/45R20 for Limited/Premier trims. Exact specifications can vary by year, trim, and market, so always verify the placard or owner’s manual before purchasing replacements. Following the recommended sizes helps preserve safety systems, ride quality, and overall performance.

What is the best tire for a Subaru Ascent?

The best tires for a Subaru Ascent depend on your driving needs, with popular options including the Michelin Defender 2 for all-season grip and longevity, the Falken Wildpeak A/T Trail for excellent wet, dry, and snow traction, and the Pirelli Scorpion AS Plus 3 for a balance of luxury and longevity. For an all-weather option that performs well in snow, consider the Michelin CrossClimate2 or the Bridgestone Weatherpeak. 
All-season

• Michelin Defender 2: Offers better stopping distances and strong all-season grip. 
• Yokohama YK-CTX: Provides high-end performance and all-season traction for CUVs. 
• Pirelli Scorpion AS Plus 3: Known for long tread life and luxurious all-season grip. 

All-weather (3-Peak Mountain Snowflake rated) 

• Michelin CrossClimate2: A versatile and safe choice, praised for excellent performance in cold, snowy, and icy conditions, as well as long highway trips. 
• Bridgestone Weatherpeak: A top-rated all-weather tire with excellent scores for handling, longevity, and traction, also Three Peak Mountain Snowflake certified. 

All-terrain

• Falken Wildpeak A/T Trail: An excellent choice for exceptional traction in wet, dry, and severe snow conditions, with a tread designed to lean towards highway use but with more aggressive grip. 

Important considerations

• Tire size: Always ensure you get the correct tire size, which can be found on the driver's side doorjamb sticker or in your owner's manual. 
• Driving conditions: The best tire for you depends on your local climate. If you get a lot of snow, an all-weather or dedicated winter tire is recommended over a standard all-season tire. 
• Tread warranty: Some tires come with a tread life warranty, which can be a consideration for a vehicle like the Ascent that is often driven long distances.
