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 drive under high speed and 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 tan δ(1)50° C. and tan δ(1)150° C. of a first rubber member, and the tan δ(2)50° C. and tan δ(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.
(tan δ(1)50° C.+tan δ(2)50° C.)−(tan δ(1)150° C.+tan δ(2)150° C.)≤0.08
(tan δ(1)50° C.+tan δ(2)50° C.)−(tan δ(1)150° C.+tan δ(2)150° C.)≤0.08
