Expert Buying Guide for 1992 GMC 3500 Regular Cab
For your 1992 GMC 3500 Regular Cab, the 8x165.1 bolt pattern is shared with 1992–1999 models, ensuring cross-compatibility. The 116.7mm center bore requires hub-centric rings for aftermarket wheels to prevent vibration. Offset is critical: stock is 20mm; deviations affect scrub radius and tire clearance.
