Tire
By installing electronic components on the inner surface of the tire and setting the ratio of the complex elastic modulus of the joint to that of the tread rubber to be less than 1, the problem of tire sensor peeling off due to large impacts during high-speed driving is solved, achieving excellent peel resistance.

Abstract
A tire with excellent peel resistance is provided, making it less prone to electronic components peeling off the tire surface even when subjected to large impacts during high-speed driving. An electronic component mounting component for housing the electronic components is mounted on the surface of an inner tire component disposed within the tire's inner cavity. The electronic component mounting component includes: an electronic component storage section for storing the electronic components and a joint portion having a mating surface for mounting the electronic component mounting component on the surface of the inner tire component. A line passing through the center point of the joint surface of the electronic component mounting component with the inner tire cavity surface and perpendicular to the tread surface profile does not pass through a circumferential groove formed on the tread surface. The complex elastic modulus E*r (MPa) of the joint portion at 30°C and the complex elastic modulus E*t (MPa) of the tread rubber constituting the tread at 30°C satisfy E*r / E*t<1.
