1. A variable wheel resonator system for a vehicle, the system comprising:
a resonator structured to have a second air chamber formed therein and an air vent formed on one side portion thereof for communication with a first air chamber within a tire, the resonator being mounted on a rim portion of a wheel;
a solenoid valve mounted on a specific position of the resonator and configured to adjust an amount of air flowing from the first air chamber to the second air chamber;
a power supply configured to provide power for a turn-on operation of the solenoid valve; and
a controller configured to control current being applied from an external power source to the power supply to suit a power supply time for turning on/off the solenoid valve and a periodic signal,
wherein the specific position of the resonator is located in a first position that is different from a second position of the air vent such that air in the first air chamber of the tire enters into the second air chamber of the resonator through the solenoid valve and then flows into the first air chamber through the air vent of the resonator.
