An automobile hub with a hollow rim includes a wheel disc and the rim with at least one hollow cavity, in which the rim includes at least two mutually nested rings and an axial end cap at the same ends of the at least two rings, and the hollow cavity consists of the rings and the axial end cap. The outer side of one end of the wheel disc includes axial rim mounting grooves, and the rim is inserted into the rim mounting grooves and fixed to the wheel disc through the end without the axial end cap. By employing the automobile hub with the hollow rim, the hub assembling method, and the automobile having the hub, the weight of the hub can be further reduced, and the hub has sufficient strength.
