Expert Buying Guide for 2015 Subaru Outback
For your 2015 Subaru Outback, the bolt pattern is 5x100 with a center bore of 56.1mm. When selecting aftermarket wheels, ensure the center bore matches or use hub-centric rings to prevent vibration. The offset should stay close to 48mm; deviations beyond ±5mm may cause rubbing or clearance issues. Always verify lug nut thread pitch (12x1.25) and seat type—use conical (60-degree) or ball-seat nuts as specified. Avoid wheels from 2016+ Outbacks (5x114.3) as they won't fit. Proper fitment ensures safety and performance.
