A method for controlling a pulley of a vehicle having a continuously variable transmission may include: determining, by a controller, a pulley target torque and a target pulley ratio, upon detecting disturbance of the vehicle; determining, by the controller, target pressures of a driving pulley and a driven pulley based on the pulley target torque and the target pulley ratio and comparing the target pressures with each other; and controlling, by the controller, a pressure of a pulley having a larger target pressure in the comparing to be a maximum pressure generatable depending on a traveling situation of the vehicle and controlling a pressure of the other pulley to be increased to a correction pressure for implementing the target pulley ratio.
