1978 Jeep J20 Wheel Fitment Guide — What Works & What to Avoid
Your 1978 Jeep J20 uses a 6x139.7 bolt pattern with a 114.6mm hub-centric center bore. The stock wheel measures 15x6 with a 3mm offset. You can upgrade to 15x7, 15x8, or step up to 16-inch, 16.5-inch, or 17-inch sizes—all the way to 17x8.5—giving you solid options for both street and off-road duty without sacrificing compatibility.
Since only the 6x139.7 bolt pattern fits your J20, verify any wheel's pattern before purchasing. Your hub measures 114.6mm, so use hub-centric rings if your chosen wheel has a larger center bore to ensure a proper fit. Aggressive offsets or wider wheels risk contact with fender wells and suspension components, so stick within the compatible sizes we've verified for your truck.
Every wheel we offer for your 1978 Jeep J20 is guaranteed to bolt on and ships free throughout the lower 48 states. You'll find quality options from Vision, Work Wheels, Fuel 1PC, OE Wheels, Carolina Forged, LOCK OFFROAD, Enkei, and Icon Alloys, all in stock and ready to ship.
