ABSTRACT:
A pneumatic tire (10) has a tread portion (11), a pair of sidewall portions (13) and a pair of bead portions (14). Each bead portion (14) has a bead core (15), and each bead core (15) has a radially inner surface defining a bead core base (31). Radially inward of, and wider than, each bead core base (31) is a bead seat profile (20). The bead seat profile (20) provides an interference fit between the tire (30) and the ledge (42) of the wheel rim (40) to which the tire (10) is to be mounted. The bead seat profile (20) has at least two portions which are inclined at specific angles with respect to the radially inner surface of the bead core base The radially inner base (31) of the bead core (15) is substantially parallel to the bead seat profile.
