Check out this 2018 GMC Sierra 1500 from the Canada Custom Autoworks fitment gallery. We mounted 20-inch Armed Off-Road Tank wheels in a 20x9 sizing (0 offset) in Black, and the difference is night and day. The Suretrac Wide Climber AWT tires in 33x12.50R20LT rated 119Q complete the setup. Full clearance, zero rubbing - exactly how a proper fitment should sit. Like what you see? This exact wheel and tire package can be ordered below, with professional installation at Canada Custom Autoworks across Western Canada.
