Expert Buying Guide for 2008 Chevrolet Silverado 3500 HD Regular Cab
For the 2008 Chevrolet Silverado 3500 HD Regular Cab, the 8x165.1 bolt pattern is shared with 2007–2011 models. The center bore is 116.6mm; aftermarket wheels with a larger bore require hub-centric rings to prevent vibration. Offset is critical: factory is 12mm, and staying within ±5mm is recommended to avoid rubbing or bearing stress. Always use lug nuts with the correct thread pitch (14x1.50) and seat type (cone seat for most aftermarket wheels). Never mix seat types. Re-torque after 50 miles of driving. Avoid wheels from 8x180 applications (2012+).
