Rough Country's 91M Series wheel brings an aggressive concave and dagger design to the Super Duty platform, finished in gloss black with milled accents that cut through the monotony of stock wheels. At 20x12 with a -44mm offset and an 8x170 bolt pattern, this single-piece aluminum wheel is built specifically for lifted F-250 and F-350 applications where deep negative offset and a wide stance matter. Exposed lug nut pockets reinforce the high-end custom look without adding unnecessary weight or complexity.
Single-piece aluminum construction. The one-piece build keeps weight down while delivering the structural rigidity heavy-duty trucks demand. No welds, no seams, no weak points, just a solid aluminum wheel ready for off-road use and daily driving alike.
Gloss black finish with milled accents. Rough Country applies a durable gloss black base coat and then mills the accent surfaces to reveal the raw aluminum beneath, creating a two-tone contrast that holds up against trail debris and road grime far better than painted-only finishes.
Exposed lug nut design. The open lug pocket layout lets you run colored or aftermarket lug nuts to personalize the wheel further, giving you a modern, high-end look that stays functional under load.
