摘要： A tire and rim combination including a flanged rim and a pneumatic tire. The tire includes a pair of bead parts each provided with a plurality of, preferably at least 8, pieces of exhaust ribs projecting from a bead outside surface and extending outwardly in a radial direction so as to form air passages for escape of air between a rim flange and the bead outside surface during rim assembly. A distance F1 from an inner end of the exhaust rib to a bead base line is in a range of 0.7 to 1.5 times a flange height FH measured from the bead base line, and a distance F2 from an outer end of the exhaust rib to the bead base line is not less than 1.1 times the flange height FH. The exhaust rib has a triangular sectional shape having a width of 0.5 to 1.0 mm and a height of 0.5 to 2.0 mm.

摘要： 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.
