Abstract: Heavy duty earthmoving vehicles operating on irregular terrain experience high vehicle-to-rim-to-tire loadings which can be accommodated by a lightweight multi-piece rim assembly employing a fluted mounting bell with a mounting ring at its outboard end and a radially disposed flange or lip at its mouth to which several inwardly directed support webs of two matching roll formed rim wall halves are bolted to complete the lightweight rim which can be mounted in a cantilevered manner through the mounting ring so a support surface formed on the inner periphery of the mouth of the mounting bell is positioned closely adjacent to a cooperating hub support ring formed on the outer surface of the hub of the vehicle on which the rim assembly is mounted. This allows the heavier loadings to be transmitted through these coacting surfaces which are located remotely from the mounting ring by which the rim is attached to the outboard end of the hub.
