1979 GMC K1500 Wheel Fitment Guide — What Works & What to Avoid
Your 1979 GMC K1500 uses a 6x139.7 bolt pattern with an 89mm hub-centric center bore. The truck left the factory on 15x6 wheels with a 10mm offset. You can fit 15x6, 15x7, 15x8, 16x7, or 16x8 sizes, giving you solid room to upgrade without hunting for fitment compromises across trims or configurations.
Keep in mind that only 6x139.7 bolts will fit this truck—no other patterns work. All our wheels ship hub-centric or with hub-centric rings included, so proper centering is handled. Watch your offset when going wider; stepping to 16-inch diameter or greater width can bring aggressive offsets into conflict with your fender and suspension geometry if you're not careful about the numbers.
Every wheel we list for your K1500 is confirmed to bolt on and ships free to the lower 48 states. We stock Vision, Work Wheels, Fuel 1PC, OE Wheels, Carolina Forged, LOCK OFFROAD, Enkei, and Icon Alloys—all ready to ship.
