Document Type and Number:
WIPO Patent Application WO/2021/070582
Kind Code:
A1
Abstract:
Provided is a pneumatic tire with which an improvement in production efficiency can be achieved and the material recycle property can be improved while ensuring stability of the grounding shape of a tire. According to the present invention, a tread reinforcing element 4 which comprises a thermoplastic resin is provided between a tire lumen surface 1H and a tire grounding surface 1S. On an arbitrary reference line X parallel to the tire equator C, the thickness center point 4P of the tread reinforcing element 4 is configured such that a distance L1 from the tire lumen surface 1H in the tire radial direction is within the range of 50-95% of a distance L0 from the tire lumen surface 1H to the tire grounding surface 1S in the tire radial direction.
