1978 Dodge Diplomat Wheel Fitment Guide — What Works & What to Avoid
Your 1978 Dodge Diplomat bolts on with a 5x114.3 pattern. The factory setup runs 15x6 wheels at a 43-millimeter offset. You can upgrade to 15x6.5, 15x7, or step up to 16x7—all bolt straight on without modification. Since this model isn't staggered, your front and rear wheels match.
The 5x114.3 bolt pattern is the only fitment that works on your Diplomat, so verify any wheel choice before purchase. All compatible wheels need to account for the 67.1-millimeter hub-centric bore; if a wheel's center bore exceeds that measurement, use hub-centric rings to ensure proper seating. Aggressive offsets or wider wheels risk interference with fenders and suspension geometry, so stick with the compatible sizes listed.
Every wheel we offer for your Diplomat is verified to fit and ships free throughout the lower 48 states. Aodhan, Heritage Wheel, Work Wheels, and Enkei are all in stock and ready to ship.
