Abstract

An object of the present disclosure is to provide a tire with improved chipping resistance. Provided is a tire comprising a tread, the tread comprising n (n represents an integer of 3 or more) rubber layers, wherein, in a case where a rubber sample comprising interfaces of a k-th rubber layer (k represents an integer of 1 or more and n-2 or less) and a k+1-th rubber layer counted from a tread surface, cut out from the tread, is irradiated with neutron rays to perform a neutron scattering measurement, and a scattering intensity when a scattering vector calculated from a scattering intensity curve thus obtained is 0.12 nm<sup>-1</sup> is defined as X<sub>k</sub> (cm<sup>-1</sup>), and a rubber sample comprising interfaces of a k+1-th rubber layer and a k+2-th rubber layer counted from the tread surface, cut out from the tread, is irradiated with neutron rays to perform a neutron scattering measurement, and a scattering intensity when a scattering vector calculated from a scattering intensity curve thus obtained is 0.12 nm<sup>-1</sup> is defined as X<sub>k+1</sub> (cm<sup>-1</sup>), | X<sub>k</sub> - X<sub>k+1</sub> | is 0.10 cm<sup>-1</sup> or less for at least one k.
