PURPOSE:To permit the suspension installation position of rear wheels to be arranged possibly outside in the direction of car width by constituting each of front and rear wheels from single tire and reducing the flatness ratio of a rear tire in comparison with that of a front tire. CONSTITUTION:The tires (long in the longitudinal direction) 2 having a relatively large flatness ratio (height in the section of tire/tire width) are installed onto front wheels 1R and 1L, and the tires 8 having each of the diameter and the flatness ratio smaller than those of the tire 2 are installed onto rear wheels 3R and 3L. The flatness ratio of the tire 8 is set to a value in the case where the rear-wheel load received normally by double tires is received only by the tires 8. Therefore, each of the width and dimension of the rear wheels 3R and 3L can be reduced in comparison with the common rear wheel constituted of double tires, and the suspension installation position for a relief spring 5, shock absorber 6, etc. can be arranged outside in the direction of car width. |
