The rear end of the frame is about twice the width of the front end and the side rails each lie in a vertical plane that is disposed at an acute angle relative to the central longitudinal axis of the frame. Single tire mount wheel and axle subassemblies are mounted to the frame. These subassemblies reduce the tare weight of the tractor trailer and additionally permit the wider frame to be utilized.
