Expert Buying Guide for 2004 Subaru Outback
For your 2004 Subaru Outback, the bolt pattern is 5x100 with a center bore of 56.1mm. When selecting aftermarket wheels, ensure they have a center bore of at least 56.1mm or use hub-centric rings to prevent vibrations. The factory offset is 48mm; staying within ±5mm is recommended to avoid rubbing or suspension interference. Always use lug nuts with the correct thread pitch (12x1.25) and seat type (cone or ball seat) to ensure proper clamping force. Mismatched lug nuts can lead to wheel loosening. Re-torque after 50-100 miles of driving.
