To provide an inflated tire capable of suppressing a separation at the end portion of a belt ply.SOLUTION: An inflated tire includes: a carcass; and first, second and third belt plies laminated in sequence on the outer circumference of the carcass at a tread from the internal side relative to a tire diameter direction to the external side relative to such a direction. The end portion of the third belt ply is located inwardly relative to the end portion of the second belt ply in the tire widthwise direction, and is located so as to be apart from the outer circumferential surface of the second belt ply in the tire diameter direction. Further provided are an inter-belt rubber placed between the end portion of the third belt ply and the outer circumferential surface of the second belt ply, and an under-belt rubber placed between the end portions of the first and second belt plies and the outer circumferential surface of the carcass. The inter-belt rubber has a higher rubber rigidity than that of the under-belt rubber, and the under-belt rubber has a smaller loss tangent tanδ than that of the inter-belt rubber.SELECTED DRAWING: Figure 1

    【課題】ベルトプライの端部でのセパレーションを抑制することができる空気入りタイヤを提供する。【解決手段】空気入りタイヤは、カーカスと、トレッドにおけるカーカスの外周にタイヤ径方向内側から外側へ向かって順に積層される第1、第2、及び第3のベルトプライと、を備え、第3のベルトプライの端部は、第2のベルトプライの端部よりもタイヤ幅方向内側に位置し、且つタイヤ径方向において第2のベルトプライの外周面から離間して位置しており、第3のベルトプライの端部と第2のベルトプライの外周面との間に配置されるベルト間ゴムと、第1及び第2のベルトプライの端部とカーカスの外周面との間に配置されるベルト下ゴムと、を備え、ベルト間ゴムは、ベルト下ゴムよりもゴム硬度が高く、且つベルト下ゴムは、ベルト間ゴムよりも損失正接tanδが小さい。【選択図】図1
