Expert Buying Guide for 2008 GMC Savana 3500 Cargo
For your 2008 GMC Savana 3500 Cargo, the 8x165.1 bolt pattern is shared with 1996–2010 models. The center bore is 116.7mm, so aftermarket wheels must have a bore ≥116.7mm; use hub-centric rings to avoid vibration. Offset is critical: stock is around 28mm. Sticking within ±10mm ensures proper clearance and load distribution. Always use the correct lug nuts: 14x1.5 thread pitch with a cone seat (60-degree). Flat or ball-seat nuts can loosen, causing wheel separation. Re-torque after 50 miles of driving.
