1979 GMC G2500 Wheel Fitment Guide — What Works & What to Avoid
Your 1979 GMC G2500 Rally, Rally STX, or Vandura uses a 5x127 bolt pattern with a 77.8mm hub-centric bore. The stock wheel is 15x6 with an 11mm offset. You can upgrade to 15x7, 15x7.5, or 15x8, or step up to 16-inch sizes from 16x6.5 through 16x8, plus 17x7, 17x7.5 options. Since this van runs square setup, both front and rear accept the same width and offset without compromise.
Remember that only 5x127 bolts onto this G2500—verify any wheel before purchase. All our wheels ship hub-centric ready, though if you choose a wheel with a bore larger than 77.8mm, we'll supply hub-centric rings to ensure a perfect fit. Stay mindful of fender and suspension geometry when selecting wider or more aggressive offsets, as this classic van has limited clearance compared to modern vehicles.
Every wheel we list for your G2500 is guaranteed to bolt on and ships free across the lower 48 states. In stock now: Black Rhino, Dirty Life, Carolina Forged, Fuel 1PC, Icon Alloys, Vision, 9Six9 Wheels, and LOCK OFFROAD. Build your perfect rolling setup today.
