1978 Mercury Bobcat Wheel Fitment Guide — What Works & What to Avoid
Your 1978 Mercury Bobcat uses a 4x108 bolt pattern shared across Base, Runabout, and Villager trims. The stock wheel measures 13x5.5 with a 36 offset. You can upgrade to larger compatible sizes including 13x6, 13x7, 14x7, 15x6.5, or 15x7, all maintaining the same non-staggered configuration throughout the vehicle.
The critical fitment rule here is that only 4x108 bolt patterns work on your Bobcat—no other patterns will thread properly. Your hub bore measures 63.9mm, so always use hub-centric rings if your chosen wheel has a larger center bore. Be cautious with aggressive offsets or extreme widths, as they risk contact with fenders or suspension components on a classic car of this era.
Every wheel we offer for your Bobcat is guaranteed to bolt on correctly and ships free to the lower 48 states. Browse our in-stock inventory from fifteen52, Motegi Racing, G-LINE ALLOYS, and Race Star to find your perfect fit.
