Expert Buying Guide for 1994 GMC Rally Wagon 2500
For your 1994 GMC Rally Wagon 2500, the 8x165.1 bolt pattern is shared with 1992–1994 models. The 116.7mm center bore is critical: aftermarket wheels often have larger bores, requiring hub-centric rings to prevent vibration and ensure load is on the hub, not the lugs. Offset is sensitive; the factory 20mm offset maintains proper scrub radius and clearance. Straying too far can cause rubbing or bearing stress. Always use 14x1.5 lug nuts with the correct seat (cone or ball) to avoid loosening. Re-torque after 50 miles of driving.
