1978 Fiat 131 Wheel Fitment Guide — What Works & What to Avoid
Your 1978 Fiat 131 rolls on a 4x98 bolt pattern with stock 13x5 wheels at 25 millimeters of offset. The car accepts wheels up to 15 inches, so you can fit 13x5, 14x5.5, 14x6, or 15x6.5 sizes—all delivering progressively sportier looks while staying mechanically sound. Since this model runs square fitment, you can choose any of these compatible sizes without worrying about front-to-rear differences.
Make certain any wheel you buy has the 4x98 bolt pattern, as nothing else will fit your Fiat. The hub center bore measures 58.1 millimeters; if a wheel's bore runs larger, use hub-centric rings to ensure proper centering. Going significantly wider or running much more aggressive offset than stock risks contact with the fender or suspension components, so stick within the listed compatible dimensions to avoid trouble.
Every wheel we list for your 1978 Fiat 131 bolts on correctly and ships free to the lower 48 states. Advan wheels are currently in stock and ready to ship, giving you a proven option for your project.
