摘要： A run-flat tire includes a carcass including at least one carcass ply, a belt layer, a pair of side reinforcing rubber layers, a pair of bead apex rubber components. A height of the one bead apex rubber component is greater than a height of the other bead apex rubber component. An inner end height of the one side reinforcing rubber layer is greater than an inner end height of the other side reinforcing rubber layer. In a radial region of the tire where at least the bead apex rubber components and the side reinforcing rubber layers are provided, the tire has a same thickness in the respective sides of the bead portions.

摘要： A tire formed from a resin material is provided having a high stress withstanding ability and capable of maintaining a high internal pressure.By configuring the side sections 14 with plural circular arc curve faced portions 32 having curvature in the circumferential direction formed successively along the circumferential direction the stress acting on the side sections 14 can be distributed at a radial direction stress and a circumferential direction stress. Accordingly, the radial direction stress can be reduced further than in a conventional profile not provided with any circular arc curve faced portions along the circumferential direction, enabling sufficient pressure withstanding ability (internal pressure) to be secured for a pneumatic tire for use on a vehicle even though a thermoplastic material with weaker stress than that of rubber is employed for the side sections 14.
