1978 Buick Opel Base Wheel Fitment Guide — What Works & What to Avoid
Your 1978 Buick Opel bolts to a 5x120.65 pattern. The factory setup runs 14x6 wheels at an 11 mm offset. You can step up to 14x7, or move to 15-inch fitments in 6, 6.5, or 7-inch widths—all maintaining the same offset without modification. Since this model uses a non-staggered setup, your front and rear wheels follow one spec.
The 5x120.65 bolt pattern is exclusive to this application, so verify any wheel matches that specification before purchasing. Your 70.3 mm hub bore requires hub-centric rings if you select a wheel with a larger center bore to ensure proper fit and balance. Aggressive offset changes or excessive widths risk contact with fenders and suspension components, so stick with the compatible sizes listed for your Opel.
Every wheel we offer for your 1978 Buick Opel is verified to bolt on correctly and ships free throughout the lower 48 states. American Racing, US Mag 1PC, Performance Replicas, Vision, E5 Wheels, WELD Performance, Forgestar, and Ridler all have in-stock options ready to ship.
