2020 Ram 3500 Big Horn Wheel Fitment Guide — What Works & What to Avoid
Your 2020 Ram 3500 Big Horn uses an 8x165.1 bolt pattern shared across Big Horn, Laramie, and most other trims. The stock wheel is an 18x8 with 57mm offset. You can fit multiple sizes: 17-inch options from 7.5 to 9 inches wide, 18-inch wheels up to 9 inches, and aggressive 20-inch sizes including 10, 12, and 8-inch widths. This truck runs a non-staggered setup, so matching all four wheels is straightforward.
All wheels for this Ram must have an 8x165.1 bolt pattern—nothing else will mount. The center bore measures 121.3mm; if you choose a wheel with a larger bore, use hub-centric rings to ensure a safe, centered fit. Wider and more aggressive offset combinations can risk contact with fenders and suspension components, so verify fitment specs carefully when moving significantly beyond the stock 57mm offset.
Every wheel we list for your 3500 bolts on correctly and ships free to the lower 48 states. In stock now are trusted brands like Carolina Forged, Vision, WELD Off-Road, American Truxx, Black Rhino, Fuel 1PC, American Racing, and Tuff—all confirmed to fit your truck.
