PURPOSE: A tire for a vehicle is provided to improve durability of tires by preventing a crack from growing from a groove. CONSTITUTION: To mount a reinforcing belt layer(6) on the lower portion of a groove(5), the reinforcing belt layer is adhered to the upper surface of an under tread in molding a tire. After that, the tire is molded by mounting a cap tread layer on the upper portion of the reinforcing belt layer. The reinforcing belt layer absorbs shock to prevent belt separation in traveling with the tire as a stone is inserted into the groove and to prevent a crack on a bottom surface(50) of the groove from growing. Therefore, the reinforcing belt layer serves to prevent the groove and a belt part(2) from being damaged.
