1988 GMC K2500 Wheel Fitment Guide — What Works & What to Avoid
Your 1988 GMC K2500 Sierra uses a 6x139.7 bolt pattern with a 78.1mm hub-centric center bore. The stock setup runs 16x6 wheels at a 10 offset. You can go up to 18 inches in diameter and progressively wider—from 16x6 all the way through 16x9, plus 17x8, 17x8.5, and 18x9—giving you solid room to customize without sacrificing fit or function.
Since this truck only accepts 6x139.7 bolts, verify that pattern before ordering. The 78.1mm center bore is hub-centric, so if your chosen wheel has a larger bore, use hub-centric rings to center it properly on the hub. Wider wheels and more aggressive offsets can risk contact with fender or suspension components, so stay conservative if you're at the extreme end of our compatible range.
We stock Vision, Work Wheels, Fuel 1PC, OE Wheels, Carolina Forged, LOCK OFFROAD, Enkei, and Icon Alloys in fitments for your K2500. Every wheel we list bolts on and ships free throughout the lower 48 states.
