Abstract
A pneumatic tire is proposed in which reduction in weight and steering stability of the tire are both achieved to a high degree. A height of a bead filler from a bead heel is from 10 to 30 mm, an inner liner layer disposed inward of a carcass layer is formed from a thermoplastic resin or a thermoplastic elastomer composition that is blended from a thermoplastic resin component and an elastomer component having a Young's modulus of from 70 to 1500 MPa and a thickness of from 0.05 to 0.25 mm, and an end of the inner liner layer is disposed farther inward in a tire radial direction than an end outward in the tire radial direction of the bead filler.
Claims17
A pneumatic tire comprising a carcass layer mounted between a pair of bead portions, the carcass layer being folded back around a bead core embedded in each of the bead portions, a bead filler disposed on the bead core, and an inner liner layer disposed inward of the carcass layer, wherein
- a height H of the bead filler from a bead heel is from 10 to 30 mm;
- the inner liner layer is formed from a thermoplastic resin or a thermoplastic elastomer composition that is blended from a thermoplastic resin component and an elastomer component having a Young's modulus of from 70 to 1500 MPa and a thickness of from 0.05 to 0.25 mm;
- and an end of the inner liner layer is disposed farther inward in a tire radial direction than an end outward in the tire radial direction of the bead filler.
