Abstract
A vehicle, such as a trailer, having a low tire warning and weight transfer system. The trailer has tandem wheel sets located on each side. The two tires of each tandem wheel set are each rotatably attached to a walking beam assembly which, in turn is attached to the trailer. The walking beam assembly has a horizontal walking beam that is substantially parallel to the ground when both tires of the adjacent wheel set are fully inflated. Walking beam stops are located on the trailer body adjacent each end of the walking beam. At least part of the stops intersect the vertical plane of the adjacent walking beam at a site above and/or below the beam. When one of the tires of a tandem wheel set becomes at least partially deflated, at least one end of the same side walking beam comes into contact with the adjacent stop, which prevents further movement of the walking beam assembly and shifts weight to the other, fully inflated tire. Upon contact of the walking beam end with the stop, a low tire signalling device is actuated.
