1. A vehicle wheel comprising:

  • a steel rim defining a first concave chamber therein; and

    an outer tire assembled on the steel rim, the outer tire defining a second concave chamber therein, the first concave chamber of the steel rim and the second concave chamber of the outer tire cooperatively defining an inner cavity in the vehicle wheel,wherein the depth of the first concave chamber of the steel rim is increased to thereby cause that a volumetric space of the first concave chamber of the steel rim is larger than that of a known concave chamber of a known steel rim, and the depth of the second concave chamber of the outer tire is decreased to thereby cause that the volumetric space of the second concave chamber of the outer tire is smaller than that of the known concave chamber of the known outer tire;

    wherein the volumetric space of the first concave chamber of the steel rim is at least a half of the volumetric space of the inner cavity, and the volumetric space of the second concave chamber of the outer tire is at most one third of the volumetric space of the inner cavity;

    wherein the distance between the circumferential edge of the steel rim and the circumferential edge of the outer tire is within a range from 0.5 cm to 5 cm;

    wherein a cross section of the second concave chamber of the outer tire is squared, or a flat underside of the outer tire is transversely flatted, or upwardly curved, under a loading pressure, the outer surface of the wheel is transversely flatted, or the outer tire is embodied as flat shape, and two sidewalls of the outer tire are eliminated;

    wherein at least one inner support is disposed within the outer tire to protect the wheel from a blowout accident.
