To provide a tire that can exert appropriate attenuation performance due to a deflection of the tire while enhancing rigidity of a case.SOLUTION: A tire side part 30 of a pneumatic tire 10 has an inside rubber layer 31 provided outside in a tire width direction of a carcass layer 40 and an outside rubber layer 36 provided outside in the tire width direction of the inside rubber layer 31. A loss tangent tanδ of the outside rubber layer 36 or tanδout is larger than a loss tangent tanδ of the inside rubber layer 31 or tanδin.SELECTED DRAWING: Figure 2
【課題】ケース剛性を高めつつ、タイヤが撓むことによる適切な減衰性を発揮し得るタイヤを提供する。【解決手段】空気入りタイヤ10のタイヤサイド部30は、カーカス層40のタイヤ幅方向外側に設けられる内側ゴム層31と、内側ゴム層31のタイヤ幅方向外側に設けられる外側ゴム層36とを有する。外側ゴム層36の損失正接tanδであるtanδoutは、内側ゴム層31の損失正接tanδであるtanδinよりも大きい。【選択図】図2
