Expert Buying Guide for 2015 Audi S8
For your 2015 Audi S8, the bolt pattern is 5x112 with a critical center bore of 66.6mm. Aftermarket wheels often have a larger bore, requiring hub-centric rings to prevent vibration and ensure proper load distribution. The offset is sensitive; stock is 42mm, but a range of 35-48mm is acceptable depending on width. Always verify lug nut thread pitch: B 14x1.50. Use ball-seat lug nuts (R13 ball radius) to match OEM wheel seats; cone-seat nuts can cause damage. Re-torque after 50-100 miles. Avoid spacers without extended studs.
