What size are the lug nuts on a Subaru Forester?

Most Subaru Forester models use M12x1.25 lug nuts with a 60-degree conical seat, and you’ll typically need a 19 mm socket to loosen or tighten them.


The exact size can vary by year, wheel type, and whether you’ve installed aftermarket wheels or locking nuts. Always verify against your vehicle’s documentation or by inspecting the nuts themselves if you’re unsure.


Common lug nut specs for Forester


Here are the typical hardware specs you’ll encounter on most Forester models. They serve as a quick reference, but verify if you use aftermarket wheels, locking nuts, or special editions.



  • Thread size and pitch: M12 x 1.25

  • Seat type: 60-degree conical (cone) seat

  • Wrench size (nut hex): 19 mm socket

  • Bolt pattern: 5x100 (typical for Forester wheels)


In short, for most Forester versions, the standard lug nut size is M12x1.25 with a 60-degree conical seat, and the lug nuts are tightened with a 19 mm socket. Always verify with your specific vehicle configuration and wheel setup.


How to confirm for your exact year and model


If you want to be certain about your car’s lug nuts, use these verification steps.



  1. Check the owner's manual or the driver’s door jamb/ fuel cap sticker for lug nut size and torque specifications.

  2. Inspect an actual lug nut or the wheel studs for stamping (look for markings such as M12x1.25 or 60-degree conical seat). If the nut is locking or aftermarket, markings may differ.

  3. Consult Subaru’s official parts catalog or call a dealership with your VIN to confirm the exact lug nut size and seat type for your year and wheel combination.


Following these steps will help ensure you’re using the correct lug nuts and torque for your Forester and avoid cross-threading or improper seating.


Summary


For most Subaru Forester models, lug nuts are M12x1.25 with a 60-degree conical seat and require a 19 mm wrench, typically with a 5x100 bolt pattern. However, variations exist with different wheels or aftermarket components, so always verify using the manual, the nuts themselves, or a dealer if uncertain.
