The present invention relates to a pneumatic tire for a vehicle capable of adjusting the rigidity of a tread improving ride comfort and steering performance by installing a piezoelectric film of which shape is change inside a block of the tread and changing the shape of the piezoelectric film to adjust the rigidity of the tread according to conditions while the vehicle drives. A pneumatic tire for a vehicle capable of adjusting the rigidity of a tread according to a desirable embodiment of the present invention including the tread composed of multiple blocks and grooves becomes in direct contact with a road surface when the vehicle drives, thereby providing a braking force and a driving force to the road surface. The present invention is characterized by including a piezoelectric film adjusting the rigidity of the tread by changing its own shape by the movement of various kinds of links assembled to a steering gear and a suspension and a sensor sensing the movement of the links assembled to the steering gear and suspension to change the shape of the piezoelectric film by transmitting electrical signals to the piezoelectric film.
