    摘要： A pneumatic tire that can achieve both the steering stability and the ride comfort, and can sufficiently improve the material recyclability. There are included a tire framework member 2 comprising bead portions 5, sidewall portions 6 and an under tread portion 7, and a ground contacting tread component 3 disposed outside the under tread portion 7. The ground contacting tread component 3 is made of a first resin material M1. the sidewall portions 6 and the under tread portion 7 are made of a second resin material M2. The bead portions are made of a third resin material M3. The tensile elastic moduli E1 to E3 of the first to third resin materials M3, respectively, satisfy E1

    摘要： A tire includes a circular tire case formed from a resin material, a belt provided at an outer side in a tire radial direction of the tire case and configured by covering a reinforcing cord by a covering resin, the reinforcing cord being provided with an adhesion layer at an outer periphery thereof, and a tread provided at an outer periphery of the belt and configured from a rubber material. The belt has a gauge set within a range of from 1.15 mm to 2.0 mm. A relationship A > B is satisfied, wherein A is a thickness of the covering resin layer from the reinforcing cord to an outer circumferential surface of the belt and B is a thickness of the covering resin layer from the reinforcing cord to the tire case. A combined gauge of the tire case and the belt is not greater than 3.5 mm.
