Expert Buying Guide for 2008 Audi TT
For your 2008 Audi TT, the bolt pattern is 5x112 with a center bore of 57.1mm. When selecting aftermarket wheels, ensure the center bore matches or use hub-centric rings to prevent vibrations. The factory offset is 50mm; staying within 45-55mm is recommended to avoid rubbing or clearance issues. Always use lug nuts with the correct thread pitch (14x1.50) and seat type (ball seat for OEM, cone seat for many aftermarket wheels). Mismatched lug nuts can lead to wheel loss. Verify that wheels from 2008-2023 Audi TT models are cross-compatible, but avoid 5x100 wheels from earlier years.
