Expert Buying Guide for 2015 GMC Savana 2500 Cargo
For your 2015 GMC Savana 2500 Cargo, the 8x180 bolt pattern is shared with 2011–2024 models, but the 124.9mm center bore is critical. Aftermarket wheels often have a larger bore (e.g., 130mm), requiring hub-centric rings to prevent vibration and ensure load is on the hub, not the lugs. Offset is sensitive: stock is 44mm; deviations affect scrub radius and clearance. Use only 14x1.5 lug nuts with the correct seat (cone or ball) to avoid loosening. Always re-torque after 50-100 miles.
