2018 Subaru Outback Center Bore

Quick specs

Center bore: 56.1 mm
Bolt pattern: 5x114.3
Thread: M12 x 1.25
Fastener: Lug nuts

The 2018 Subaru Outback uses a 56.1 mm center bore across the supplied 2.5i and 3.6i configurations. The listed OEM wheel sizes range from 17 to 19 inches, but the hub bore remains the same at 56.1 mm.

For aftermarket wheels, a bore larger than 56.1 mm can leave a gap at the hub and may require a hub-centric ring sized to the wheel bore and the 56.1 mm vehicle hub. A wheel with a smaller center bore cannot be installed. The Outback also uses a 5x114.3 bolt pattern, but that match alone does not confirm compatibility.
