1981 GMC G2500 Wheels & Rims
Shop Wheels for 1981 GMC G2500
The 1981 GMC G2500 Rally, Rally STX, and Vandura models all share the same five-lug, 127mm bolt pattern. Your truck rolled off the lot on 15x6 wheels, and we've verified that every upgrade in our inventory bolts directly onto that proven setup. Choose from trusted brands like Black Rhino, Fuel, Icon Alloys, and more—all confirmed to fit your G2500.
Upgrade to a larger 15, 16, or 17-inch wheel without worrying about fitment headaches. We carry options from 15x6 up through 17x7.5, each one verified to mount securely on your truck's hub. Every wheel ships free to the lower 48 states, so you can transform your G2500's stance without the shipping stress.
1981 GMC G2500 Wheel Fitment Guide — What Works & What to Avoid
Your 1981 GMC G2500 uses a 5x127 bolt pattern and rolls on 15x6 wheels with an 11-millimeter offset from the factory. You can go up to 17 inches in diameter, with widths ranging from 6 to 8 inches depending on size. Since this van doesn't run staggered fitment, you're free to choose any compatible combination that suits your style and performance needs.
Watch for wheels that don't match the 5x127 bolt pattern—nothing else will fit your G2500. Your hub has a 77.8-millimeter center bore, so if your wheel's bore is larger, use hub-centric rings to ensure proper centering. Be cautious with wider or more aggressive offsets, as they risk rubbing your fenders and suspension components.
Every wheel we list bolts straight on and ships free across the lower 48 states. We stock Black Rhino, Dirty Life, Carolina Forged, Fuel 1PC, Icon Alloys, Vision, 9Six9 Wheels, and LOCK OFFROAD—all proven fitments for your van.
