1979 GMC C2500 Wheel Fitment Guide — What Works & What to Avoid
Your 1979 GMC C2500 uses a 6x139.7 bolt pattern with a factory 16x5.5 wheel at 13mm offset. You can upgrade to wider sizes including 16.5x6.5, 16x7, 16x7.5, 16x8, 16x8.5, 17x8, 17x8.5, 18x8.5, or 20x8.5. Since this truck rolls non-staggered, any compatible size works front and rear without worrying about different setups per axle.
Pay close attention to the 6x139.7 bolt pattern—it's the only pattern that fits this generation GMC. The 78.1mm center bore is hub-centric, so if you select a wheel with a larger bore, use hub-centric rings to ensure proper fitment. Wider wheels or aggressive offsets can interfere with fenders and suspension components, so choose sizes and offsets carefully to avoid rubbing issues.
Every wheel we offer for your C2500 is verified to bolt on safely and ships free throughout the lower 48 states. Browse our in-stock selection from Vision, Work Wheels, Fuel 1PC, OE Wheels, Carolina Forged, LOCK OFFROAD, Enkei, and Icon Alloys to find the perfect fit for your truck.
