PURPOSE:To allow doubling of a tire for steering wheels so as to improve the strength of the wheels against the load and the pressure resistance of the tire against a road surface by setting an axle shaft in a knuckle and fixing the tire to this axle shaft one by one through a bearing, respectively. CONSTITUTION:A tire for steering wheels is doubled by setting an axle shaft in a knuckle and fixing the tire to this axle shaft one by one through a bearing, respectively. In this case, the toe-in angle and chamber angle of each tire are set in proportion to the distance up to each tire measured from a king-pin acting as an origin. In addition, when the tire of driving steering wheels is doubled, a driving shaft from central T type differential gears is divided into two on this side of a knuckle that is, the driving shaft of outside wheels from the hollow section of a hollow knuckle axle shaft and the driving shaft of inside wheels from the outside of the hollow knuckle axle shaft by linear type differential gears and driving force is transmitted.
