1979 GMC Caballero Wheel Fitment Guide — What Works & What to Avoid
Your 1979 GMC Caballero bolts on five-lug wheels spaced at 5x120.65 millimeters. The factory setup runs a 14x6 wheel with a 5-millimeter offset. You can step up to 15, 16, 17, or 18-inch wheels depending on your preferred stance, with widths ranging from 6 to 8.5 inches across those sizes. Since this truck wears the same size front and rear, you don't need to worry about staggered versus square fitment.
Keep in mind that only the 5x120.65 bolt pattern will fit your Caballero—no exceptions. Your hub's center bore measures 70.3 millimeters, so if you choose a wheel with a larger bore, use hub-centric rings to ensure a proper fit and balance. Jumping too far beyond stock dimensions in width or running a very aggressive offset can invite rubbing against the fender or suspension components, so verify your chosen size sits comfortably before committing.
Every wheel we stock for your truck is verified to bolt on safely. We offer free shipping to the lower 48 states on all orders. Check out our selection from American Racing, Ridler, US Mag 1PC, and Performance Replicas, plus WELD Performance, Forgestar, Vision, and E5 Wheels—all ready to ship.
