The Econoline 12 Ton Multi-Max Trailer models features four of our patented axles rated at 5000 lbs each with each axle containing a 3 inch-6 leaf spring system. Each axle comes standard with two solid steel 8-lug wheels with 800x14.5-14 ply tires to maximize safe load carrying capabilities. The tires have a single tire load capacity of 3,030 lbs. The Multi-Max Suspension has several advantages over dual tandems, including, increased bearing capacity, lower deck height, lower center of gravity, wider mainframe, superior load stability and a smoother ride.
