1981 GMC C2500 Wheel Fitment Guide — What Works & What to Avoid
Your 1981 GMC C2500 requires 6x139.7 bolt pattern wheels. The truck rolled off the line on 16x5.5 wheels with a 13-millimeter offset. You can upgrade to larger diameters and widths, ranging from 16.5x6.5 all the way up to 20x8.5, giving you plenty of customization options to match your truck's style and performance needs.
Since this model uses 6x139.7 bolts exclusively, any wheel you choose must match that pattern precisely. The center bore measures 78.1 millimeters; if your new wheel's bore exceeds this, use hub-centric rings to ensure a proper fit. Avoid wheels with aggressively negative offsets, as too much poke can cause rubbing against fenders and suspension components.
Every wheel we offer for your C2500 is confirmed to bolt on straight, and all orders ship free throughout the lower 48 states. We stock proven brands like Vision, Work Wheels, Fuel 1PC, and OE Wheels, all ready to upgrade your classic GMC.
