The present invention relates to a pneumatic tire which controls the deformation of a bead generated by the compressed air existing between a bead part and a rim flange and improves heat radiation effects. The pneumatic tire comprises: multiple radiating grooves which are formed in the outer surface of the bead part at uniform intervals; and an exhaust line of which one surface comes in contact with the ends of the radiating grooves to be connected to the radiating grooves. |
