Off Road Monster Wheels M50 RBR Candy Red/Black Ring | 20x9.5 -12mm | 8x165.1 | HD Truck Wheel
Is This for You?
You're running an HD truck on the 8x165.1 bolt pattern — pre-2011 GM HD or Ram 2500/3500 — single rear wheel — and you want a 20" wheel with a candy red face and black ring accent that makes a bold color statement. The M50 RBR at 20x9.5 with -12mm offset delivers a moderate stance that works well on leveled and mildly lifted HD builds. Cast aluminum 1-piece construction, 125.2mm hub-centric bore, 3,500 lb load rating.
