1977 GMC C35 Base Wheel Fitment Guide — What Works & What to Avoid
Your 1977 GMC C35 uses an 8x165.1 bolt pattern with a 117.0mm hub-centric center bore. The truck rolled off the line on 16x6 wheels at a 13mm offset. You can fit anything from 16.5x6 up to 17x9, giving you solid room to customize the look while maintaining compatibility across the Base, High Sierra, Sierra Classic, and Sierra Grande trims.
Since only 8x165.1 bolts will fit your C35, verify any wheel's bolt pattern before ordering. The center bore sits at 117.0mm; if your chosen wheel has a larger bore, hub-centric rings keep things properly centered. Aggressive widths or deeply negative offsets risk interference with the fender and suspension, so stick within the listed sizes to avoid clearance headaches.
Every wheel we stock for your truck is verified to bolt on straight, and all orders ship free throughout the lower 48 states. Carolina Forged, Vision, WELD Off-Road, American Truxx, and Fuel 1PC are just a few of the quality brands ready to ship for your C35.
