Abstract
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.
