What stud pattern is a Subaru Outback?
The Subaru Outback uses a 5-lug wheel pattern on a 100 mm bolt circle (5x100).
This article explains what that means, why it matters for wheel and tire choices, and how to verify compatibility for your specific Outback model year.
What the 5x100 bolt pattern means
A bolt pattern describes how many lug studs a wheel has (five, in this case) and the spacing between them around the wheel hub (100 mm in diameter). For the Outback, the five lugs are positioned at equal angles around a 100 mm circle. This figure guides whether aftermarket rims will align with the wheel hub and center bore.
Practical implications for owners
Because the pattern is shared with many Subaru models, many aftermarket wheels marketed for Subarus will specify 5x100 compatibility. However, you should still verify other fit factors such as wheel offset, center bore size, brake clearance, and whether the wheels are designed for all seasons, winter, or performance tires.
Generational consistency and cross-compatibility
From its early iterations to current versions, the Outback has used the same 5x100 bolt pattern. This makes it possible to swap wheels within the Subaru lineup without adapters, though this does not guarantee compatibility with every year or with components like upgraded brakes or different calipers. For any wheel change, verify fitment with your specific model year and trim.
How to verify your specific vehicle
To confirm your Outback's bolt pattern, check the owner's manual or the door jamb placard for wheel specification. If you are unsure, your Subaru dealer or a trusted tire shop can measure the pattern and confirm that the wheels you choose will fit without risk to the hubs or braking system.
Summary
In short, the Subaru Outback uses a 5-lug, 100 mm bolt pattern (5x100). This standard across most generations simplifies wheel swaps, but owners should still check additional fit factors—center bore, offset, and brake clearance—before purchasing aftermarket wheels or tires. Always confirm with model-year-specific documentation or a professional when in doubt.
