1981 GMC C3500 Base Wheel Fitment Guide — What Works & What to Avoid
Your 1981 GMC C3500 uses an 8x165.1 bolt pattern with a 117.0mm hub-centric center bore. The stock wheel is 16x7 with a 13mm offset. You can step up to larger sizes including 16.5x6, 16x6 through 16x8.5, or 17-inch options up to 17x9, all in a square setup that matches your truck's original non-staggered configuration.
Since only 8x165.1 bolts fit this truck, verify your wheel choice before ordering. Your center bore is 117.0mm; use hub-centric rings if a wheel's bore is larger to ensure proper fit. Aggressive offsets or wider widths risk rubbing the fenders or suspension components, so stay within the compatible size range we've listed.
Every wheel we list bolts straight on and ships free across the lower 48 states. Carolina Forged, Vision, WELD Off-Road, American Truxx, Black Rhino, Fuel 1PC, American Racing, and Tuff all have options in stock for your C3500 right now.
