1991 GMC K1500 Wheel Fitment Guide — What Works & What to Avoid
Your 1991 GMC K1500 Sierra uses a 6x139.7 bolt pattern with a 78.1mm hub-centric center bore. The factory setup runs 15x6 wheels at a 10mm offset. You can step up to 15x7, 15x8, or move to 16-inch sizes ranging from 16x6 through 16x8.5, plus 17 and 18-inch options, all on the same non-staggered configuration.
Pay attention to the 6x139.7 bolt pattern—nothing else will fit your K1500. Since your wheels must be hub-centric, use hub-centric rings if you choose a wheel whose center bore exceeds 78.1mm. Aggressive offset or excessively wide wheels risk contact with fenders and suspension components, so verify fitment before committing to any plus-size setup.
Every wheel we list bolts straight onto your truck and ships free across the lower 48 states. Check our in-stock inventory from brands like Vision, Work Wheels, Fuel 1PC, and Carolina Forged to find the right look for your Sierra.
