Abstract

Provided is a tire in which cracks do not occur in the tire inner member during high-speed running and the occurrence of tire air leakage and detachment of electronic component mounting members is suppressed. A tire in which an electronic component mounting member for a built-in electronic component is mounted on the surface of a tire inner member, wherein the electronic component mounting member has an electronic component storage portion for storing an electronic component and a joint portion equipped with a joint surface for mounting the electronic component mounting member on the surface of the tire inner member, and the acetone extraction weight AEr (mass %) of the electronic component mounting member and the acetone extraction weight AEi (mass %) of the tire inner member satisfy (formula 1). A ⁢ E r / A ⁢ E i > 1 ( formula ⁢ 1 )
