Pneumatic tire

A pneumatic tire comprising

• a carcass extending between a pair of bead portions through a tread portion and a pair of sidewall portions, and
• a band made of at least one spirally wound cord disposed radially outside the carcass in the tread portion,
• wherein
• the band cord consists of materially identical high-strength high-modulus organic filaments, and the band cord is obtainable by the following process (1) or (2):
• (1) the high-modulus organic filaments are divided into a plurality of bunches, the bunches are each first twisted separately from each other, the first twisted bunches are each subjected to a dip-and-stretch treatment, and the treated bunches are second twisted together;
• or
• (2) the high-modulus organic filaments are divided into a plurality of bunches, the bunches are each first twisted separately from each other, the first twisted bunches are each subjected to a dip-and-stretch treatment, some of the treated bunches are second twisted together to form a core, and at least one remaining treated bunch is spirally wound around the core, whereby
• the band cord has a load-elongation curve comprising a low-modulus zone between the origin and a boundary point and a high-modulus zone between the boundary point and the breaking point, and the boundary point is at a certain elongation in a range of from 1 to 7%, and
• the ratio EH/EL of a nominal elastic modulus EH of the high-modulus zone and a nominal elastic modulus EL of the low-modulus zone is in a range of from 2.0 to 10.0.
