A wheeled work vehicle includes: a transmission transmitting the rotational power of a travelling hydraulic motor to wheels; a travelling control valve having an interruption position that interrupts supply of hydraulic fluid from a hydraulic pump to the travelling hydraulic motor; a shift changeover valve that shifts the speed stage of the transmission by the position of the shift changeover valve being selectively switched; and a controller that controls the travelling control valve and the shift changeover valve. The controller switches the travelling control valve to the interruption position, then switches the position of the shift changeover valve such that the speed stage of the transmission is shifted to the low speed stage, and switches the travelling control valve from the interruption position to an original position side before the switching in a case where the controller shifts the transmission from the high speed stage to the low speed stage.
