1988 Chevrolet G20 Wheel Fitment Guide — What Works & What to Avoid
Your 1988 Chevrolet G20 (Beauville, Chevy Van, or Sportvan) rolls on a 5x127 bolt pattern with a 77.8mm hub bore. The stock wheel is 15x6 with an 11mm offset. You can upgrade to 15-inch widths up to 8 inches, move to 16-inch sizes from 6.5 to 8 inches wide, or fit 17-inch wheels at 7 inches wide. All wheels mount as a square setup on this van.
The 5x127 bolt pattern is your only option—no other pattern will fit. Because your van's hub bore measures 77.8mm, always verify a wheel's center bore matches or use hub-centric rings if it runs larger. Stepping up to wider or more aggressive offsets risks contact with fender and suspension components, so stay within the compatible sizes listed to avoid clearance issues.
Every wheel we offer for your G20 is verified to bolt on properly and ships free throughout the lower 48 states. Black Rhino, Dirty Life, Carolina Forged, Fuel 1PC, Icon Alloys, Vision, 9Six9 Wheels, and LOCK OFFROAD all have in-stock options that fit your van perfectly.
