To provide a tire wheel of an automobile to be safely used while maintaining frictional force with the ground surface on the other half side even when one side of a tread surface is asymmetrically worn out since there is freedom to use the tire wheel by changing both surfaces to each other on the same shaft end mounting part of the automobile and to economize driving of the automobile.

This tire wheel of the four-wheel automobile is integrally provided with a spoke part between a central hub part and a rim part on the outside to fit a tire, the hub part is formed at a central position of rim width and both fastening surfaces of the hub part are formed at a front and back objective position with a rim width central line as its center so that the both surfaces of the hub part respectively become the fastening surfaces for a shaft end mounting part of an axle.
