1976 GMC G25 Wheels & Rims
Shop Wheels for 1976 GMC G25
The 1976 GMC G25 Rally, Rally STX, and Vandura all share the same straightforward five-lug bolt pattern. Factory G25 models rode on 15x6 wheels, establishing a classic baseline for this generation. We've verified every wheel we offer for your truck to ensure a perfect bolt-on fit, and they ship free throughout the lower 48 states.
Whether you're seeking a modest upgrade or a dramatic transformation, ThreePiece.us stocks wheels from respected manufacturers including Black Rhino, Dirty Life, Carolina Forged, and Icon Alloys. Your G25 can accommodate options ranging from 15-inch to 17-inch diameters across multiple widths, giving you genuine flexibility in achieving your preferred stance and aesthetic.
1976 GMC G25 Wheel Fitment Guide — What Works & What to Avoid
Your 1976 GMC G25 Rally, Rally STX, or Vandura uses a 5x127 bolt pattern with a 77.8mm hub-centric center bore. The stock setup runs 15x6 wheels at 11mm offset. You can upgrade to larger diameters—15x7, 15x7.5, or 15x8—or step up to 16-inch sizes in 6.5, 7, 7.5, or 8-inch widths, plus 17-inch options in 7 or 7.5-inch widths, all without sacrificing fitment.
Only wheels with a 5x127 bolt pattern will bolt on securely; verify this before ordering. Since your truck's center bore is 77.8mm, use hub-centric rings on any wheel with a larger bore to ensure proper centering and vibration-free operation. Wider or more aggressive offsets can risk rubbing the fender or suspension, so stick within the compatible sizes listed to avoid costly clearance issues.
Every wheel we stock for your G25 is verified to bolt on and ships free throughout the lower 48 states. Check out our in-stock selection from Black Rhino, Dirty Life, Carolina Forged, Fuel 1PC, Icon Alloys, Vision, 9Six9 Wheels, and LOCK OFFROAD—all ready to fit your classic GMC.
