WIPO Patent Application WO/2019/054213

Kind Code:

A1

Abstract:

Provided is a tire structure technology with which sufficient reading performance can be maintained even when a tire having an electronic component provided therein is caused to travel at high speed with severe handling. A pneumatic tire in which an electronic component is provided farther outward in a tire axial direction than a carcass, and in which the E*(1)50°C at 50°C and E*(1)150°C at 150°C of a first rubber member, and the E*(2)50°C at 50°C and E*(2)150°C at 150°C of a second rubber member, satisfy the following formula, where the first rubber member is a tire rubber member that has the greatest E* at 50°C among tire rubber members positioned inward from the electronic component in the tire axial direction, and the second rubber member is a tire rubber member that has the greatest E* at 50°C among tire rubber members positioned outward from the electronic component in the tire axial direction. (E*(1)50°C/E*(2)50°C) - (E*(1)150°C/E*(2)150°C) ≥ 1.0
