摘要： A pneumatic tire in accordance with the present invention includes two annular bead portions, a carcass, and a belt reinforcement layer. The carcass extends between the bead portions through sidewall portions and a tread portion. The carcass has at least one carcass ply of parallel cords turned up about the bead portions. The belt reinforcement layer is disposed radially outside the carcass and radially inside the tread portion. Each annular bead portion includes an annular bead core having the carcass ply turned up around the bead core, a first apex disposed adjacent and radially outward of the bead core, a second apex disposed axially outward of the bead core and the carcass ply, a first chafer disposed adjacent the carcass ply and axially outward of the bead core, and a second chafer disposed adjacent and axially outward the second apex and axially inward a sidewall portion. The first apex comprises a material with a 100 percent modulus between 1.0 MPa and 6.0 MPa. The second apex comprises a material with a 100 percent modulus between 1.0 MPa and 6.0 MPa. The first chafer comprises a material with a 100 percent modulus between 2.0 MPa and 4.0 MPa. The second chafer comprises a material with a 100 percent modulus between 1.0 MPa and 6.0 MPa. The sidewall portions comprise a material with a 100 percent modulus between 1.0 MPa and 2.0 MPa.
