The M44 Cannon Wheel by MSA Wheels is defined by its industrial style and technical lines, accented with circular windows and available in Satin Black finish. What are beadlock wheels and why should I consider them? Beadlock wheels clamp the bead of the tire to the wheel though the use of a beadlock ring and a series of bolts. This type of wheel was originally developed for military vehicles, allowing them to run lower air pressure and handle larger torque loads. What's that mean for you? By airing down your tires you increase the tread patch of your tire that makes contact with the ground meaning you get more traction. The downside to airing down your tires on traditional non-beadlock wheels is that the tire can come loose from the wheel and leave you stranded. A beadlock prevents that from happening and allows you to conquer any terrain and adventure further.
