PURPOSE: A tire for a vehicle equipped with an improved groove is provided to reduce deformation through restricting the bending and stretching of a groove bottom portion. CONSTITUTION: A tire for a vehicle equipped with an improved groove comprises a tread(1), a side wall, a bead, and a blocking member(4). A groove(2) is formed in the tread. The side wall is installed in the both sides of the tread. The bead is formed in the both sides of the side wall. The blocking member is formed in one or more side walls(3, 31) in the bottom portion of the groove. The blocking member blocks the contact of the side walls and prevents the narrowing of sides walls.
