1979 GMC Jimmy Wheel Fitment Guide — What Works & What to Avoid
Your 1979 GMC Jimmy bolts up to a 5x120.65 pattern with a 70.3mm hub bore. The factory wheel measures 15x6 with a 45mm offset. You can fit anything from 15-inch up to 18-inch diameters, choosing widths between 6 and 8.5 inches depending on size. Since this Jimmy runs the same fitment across all trims, your options remain consistent whether you own a Base or Sierra Grande model.
Only the 5x120.65 bolt pattern will thread onto your Jimmy's hubs—verify any wheel against this spec before ordering. The 70.3mm center bore is hub-centric, so use hub-centric rings if a wheel's bore measures larger. Aggressive offsets or very wide wheels can create rubbing at the fender or suspension, so stick within the compatible sizes listed to avoid fitment headaches.
Every wheel we stock for your Jimmy arrives ready to bolt on and ships free to the lower 48 states. American Racing, US Mag 1PC, Performance Replicas, Vision, and Forgestar are all in inventory now, giving you classic and modern styling options that fit your classic truck perfectly.
