Shop Wheels for 1977 GMC C15
Your 1977 GMC C15 came equipped with a 15x6 wheel wearing a 10 offset on a 5x127 bolt pattern.

Upgrading your truck's stance has never been easier. We stock wheels in multiple sizes from 15x6 up to 16x8, giving you flexibility to customize your High Sierra, Sierra Classic, or any other variant. Every wheel we offer for your GMC has been individually verified for proper fitment on your specific bolt pattern and center bore, ensuring a flawless installation every time.
1977 GMC C15 Wheel Fitment Guide — What Works & What to Avoid
Your 1977 GMC C15 uses a 5x127 bolt pattern with a stock 15x6 wheel at 10 offset. You can step up to 15x6.5, 15x7, 15x8, 16x7, or 16x8 while maintaining proper fitment. Since this truck doesn't run staggered sizing, any compatible size works equally well front and rear, giving you flexibility in your upgrade choice.
Make sure any wheel you choose has a 5x127 bolt pattern—no other pattern will fit this GMC. The center bore measures 78.1mm; use hub-centric rings if your wheel's bore exceeds this diameter to ensure a safe, vibration-free mount. Aggressive offsets or very wide wheels risk rubbing the fender and suspension, so stay within the compatible sizes listed to avoid clearance problems.
Every wheel we stock for your C15 is bolt-on ready and ships free throughout the lower 48 states. Black Rhino, Dirty Life, Fuel 1PC, and Icon Alloys are among the quality brands currently in stock and sized to fit your truck perfectly.
