TIRE

摘要

An object of the present invention is to achieve a reduction in weight while securing strength to counter internal pressure in a tire employing a resin material in a tire frame member.;A tire (10) includes: a tire frame member (12) formed from a resin material, and provided with side sections (18) positioned at each tire width direction side, and a crown section (22) that is connected to tire radial direction outer side end portions of the side sections (18) and that extends toward the tire width direction inner side; a reinforcement layer (14) that is provided at the outer peripheral side of the crown section (22), and that includes a cord (30) wound in a spiral along a tire circumferential direction; and a thinned portion (16) that is provided at a tire width direction central portion of the crown section (22) within the width of the reinforcement layer (14) and over a narrower range than the width of the crown section (22).
