2018 Ram 3500 Big Horn Wheel Fitment Guide — What Works & What to Avoid
Your 2018 Ram 3500 Big Horn uses an 8x165.1 bolt pattern shared across Big Horn, Laramie, and SLT trims. The stock wheel is 17x6 with 127 offset. You can fit square sizes from 17x6 through 22x12, giving you flexibility to go bigger without staggered setups. Popular upgrades include 20x10, 20x12, and 22-inch options while maintaining the same offset range that suits your truck.
Watch for the 121.3mm hub-centric bore: if your wheel's center hole exceeds that, use hub-centric rings to seat properly. Only 8x165.1 bolts on this truck, so verify before ordering. Going significantly wider or choosing aggressive negative offsets risks contact with fenders and suspension components, so stick within proven fitments for your Ram.
Every wheel we list bolts straight on and ships free to the lower 48 states. In stock now are Carolina Forged, Vision, WELD Off-Road, American Truxx, Black Rhino, Fuel 1PC, American Racing, and Tuff—all verified to fit your 3500.
