Document Type and Number:
WIPO Patent Application WO/2019/054210
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 tanδ(1)50°C and tanδ(1)150°C of a first rubber member, and the tanδ(2)50°C and tanδ(2)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 outward 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 inward from the electronic component in the tire axial direction. (tanδ(1)50°C + tanδ(2)50°C) - (tanδ(1)150°C + tanδ(2)150°C) ≤ 0.08
