The Wheel Storage and Transport (WST) I fits up to 6 ea HMMWV wheel assemblies while stacking two-high in a 20ft container, increasing the capacity of a 20ft container to 60 ea HMMWV wheel assemblies. The pivoting front gate, secured by two standard cargo straps, and adjustable side walls enable fit for most military wheels. We have developed an extender (SC-WS-LG-GT-61) for the largest wheels, of 52" and up.
