9 Claims

1. A pneumatic tire provided with an electronic component at a position outside of a carcass in a tire axial direction, wherein:

E*(1)_{50° C.}at 50° C. and E*(1)_{150° C.}at 150° C. of a first rubber member having a largest E*(50° C.) at 50° C. among rubber members for the tire located inward in the tire axial direction from a position where the electronic component is provided, and

E*(2)_{50° C.}at 50° C. and E*(2)_{150° C.}at 150° C. of a second rubber member having a largest E*(50° C.) at 50° C. among rubber members for the tire located outward in the tire axial direction from a position where the electronic component is provided, E*(1)_{50° C.}is larger than E*(2)_{50° C.}, and satisfy the following formula:

(E*(1)_{50° C.}/E*(2)_{50° C.})−(E*(1)_{150° C.}/E*(2)_{150° C.})≥1.0.
