1977 GMC K15 Wheel Fitment Guide — What Works & What to Avoid
Your 1977 GMC K15 accepts a 6x139.7 bolt pattern wheel. The truck rolls on a stock 15x6 wheel with a 10mm offset. You can upgrade to 15x7, 15x8, 16x7, or 16x8 sizes while maintaining proper clearance and suspension geometry on this non-staggered setup.
Keep in mind that only the 6x139.7 bolt pattern fits your K15—no other pattern will work. The hub center bore measures 89.0mm; if your wheel's bore exceeds this, use hub-centric rings to ensure a proper fit. Pushing too wide or running excessively aggressive offsets risks contact with fenders and suspension components, so stick within the compatible sizes listed.
We verify every wheel bolts straight onto your truck and ship free to the lower 48 states. Vision, Work Wheels, Fuel 1PC, OE Wheels, Carolina Forged, LOCK OFFROAD, Enkei, and Icon Alloys all have options in stock for your K15 right now.
