Off Road Monster Wheels M50 GBBR Gloss Black/Black Ring | 20x9.5 -12mm | 8x165.1 (8x6.5") | HD Truck Wheel
Is This for You?
You're running an HD truck on the 8x165.1 (8x6.5") bolt pattern — pre-2011 GM HD, Ram 2500/3500, or classic Ford — single rear wheel — and you want a 20" wheel with a gloss black face and black ring accent that delivers a clean, fully blacked-out look. The M50 GBBR 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.
