ABSTRACT:
A pneumatic tire to be mounted on a normal rim, has a pair of bead parts each having a bead bottom surface seating on a rim seat of the normal rim and bead outside surface connecting with the bead bottom surface and abutting against a rim flange of the normal rim. The bead outside surface is provided with an exhaust extending outward in the radial direction from an inner end of the exhaust so as to form the air passage for escape of air between the rim flange and bead outside surface at the time of rim assembly. The inner end of the exhaust is positioned within a region remote from a bead base line by a distance of 0.5 to 1.5 times a separating point height Fh defined as a height in the radial direction from the bead base line to a separating point at which the bead outside surface separates from the rim flange.
