1981 GMC G1500 Wheel Fitment Guide — What Works & What to Avoid
Your 1981 GMC G1500 Rally, Rally STX, or Vandura mounts on a 5x127 bolt pattern. The factory setup runs 15x6 with an 11-millimeter offset. You can step up to 15-inch widths through 15x8, jump to 16-inch sizes from 16x7 to 16x8, or go modern with 17-inch wheels in 17x7 or 17x7.5—all compatible with your van's suspension and body.
The 5x127 bolt pattern is the only pattern that fits this truck; confirm your current wheels match before ordering. Your hub requires wheels with a 77.8-millimeter center bore, and we supply hub-centric rings free if your new wheel's bore runs larger. Wider wheels and aggressive offsets can contact the fender or suspension, so verify your choice against your intended fitment before purchase.
Every wheel we list bolts directly onto your G1500 and ships free throughout the lower 48 states. Black Rhino, Dirty Life, Carolina Forged, Fuel 1PC, Icon Alloys, Vision, 9Six9 Wheels, and LOCK OFFROAD all carry applications in stock for your van.
