Abstract
A pneumatic tire having a tordial tire framework member having bead portions, sidewall portions and an under tread portion, and a ground contacting tread component disposed radially outside the under tread portion. The ground contacting tread component is made of a first resin material. The sidewall portions and the under tread portion are made of a second resin material. The bead portions are made of a third resin material. The tensile elastic moduli E1 to E3 of the first to third resin materials M3, respectively, satisfy E1<E2<E3.
