1991 GMC G2500 Wheel Fitment Guide — What Works & What to Avoid
Your 1991 GMC G2500 Rally, Rally STX, or Vandura uses a 5x127 bolt pattern with a 77.8mm hub bore. The factory wheel is 15x6 with an 11mm offset. You can upgrade to 15-inch widths up to 15x8, jump to 16-inch sizes ranging from 16x6.5 to 16x8, or go modern with 17-inch wheels in 17x7 or 17x7.5. This van runs a square setup, so matching wheel and offset across all four corners keeps your truck balanced and true.
Since your van's bolt pattern is 5x127, any wheel you choose must match that spec exactly—no exceptions. The 77.8mm center bore is hub-centric, so if your new wheel has a larger bore, install hub-centric rings to ensure a proper fit and safe ride. Aggressive offsets or excessively wide wheels risk rubbing against the fender wells and suspension components, so stick within the listed compatible sizes to avoid costly trimming or damage.
Every wheel we list for your G2500 is verified to bolt on safely and ships free throughout the lower 48 states. We stock Black Rhino, Dirty Life, Carolina Forged, Fuel 1PC, Icon Alloys, Vision, 9Six9 Wheels, and LOCK OFFROAD—all ready to transform your van's stance today.
