PURPOSE: A wheel for a vehicle is provided to suitably control the tire pressure as a vehicle speed, by installing a movable mass body, which is movable by the centrifugal force, in the inner of a spoke connecting between a rim and a hub, so that a fuel efficiency, a ride, and a braking force are improved. CONSTITUTION: A wheelcomprises : a rim(12) to have a projected edge and a dented middle part; a hub(14) to be fixed on the outer surface of a wheel hub; several spokes(16) to connect the rim with the hub and to be projected radically from the hub; a hollow part to be formed in the spokes ; a movable mass body to be installed on the hollow part, to be connected with the one end of a spring, whose the other end is fixed to an inner face of the rim, and to be moved along the outer circumference of a wheel by the centrifugal force; a penetrated part(21) to be connected with the hollow part and to be formed on the rim.
