Expert Buying Guide for 2008 Volvo S40
For your 2008 Volvo S40, the bolt pattern is 5x108 with a center bore of 63.4mm. When selecting aftermarket wheels, ensure they have a larger center bore and use hub-centric rings to prevent vibrations. The factory offset is 46mm; deviations beyond ±5mm may cause rubbing or clearance issues. Always verify lug nut thread pitch (12x1.5) and seat type—Volvo uses conical (60-degree) seats. Using incorrect lug nuts can lead to wheel loss. Wheels from 2006–2011 S40 models are direct fit, but avoid 4x114.3 patterns from earlier years.
