Document Type and Number:
WIPO Patent Application WO/2017/099202
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a tire in which cracks in the surface of a sidewall section are unlikely to develop. This tire is characterized in that at least part of a sidewall section thereof comprises a depth part I that satisfies the requirements indicated below and that is present from a point on the outer surface of the sidewall section to a depth of 0.5 mm. Requirements regarding the depth part I: said depth part I comprises a natural rubber, a butadiene rubber, and a thermoplastic elastomer; the peak temperature T1 (°C) of tanδ is -20°C to -5°C inclusive; and α1 ≤ 0.90 and E'1 ≥ 5 MPa when tanδ at the peak temperature T1 (°C) is denoted by á1 and the storage elastic modulus at the peak temperature T1 (°C) is denoted by E'1 (MPa).
