Expert Buying Guide for 2018 GMC Savana 2500 Passenger
For the 2018 GMC Savana 2500 Passenger, the 8x180 bolt pattern and 124.9mm center bore are critical. Aftermarket wheels require hub-centric rings to prevent vibration and ensure load support. The 44mm offset is sensitive; deviations affect scrub radius and clearance. Always use 14x1.5 lug nuts with correct seat type (cone or ball) matching the wheel. Improper thread pitch or seat can cause wheel loss. Verify wheel load rating exceeds GVWR. Cross-compatible with 2011–2024 Savana 2500 models.
