To improve high speed durability performance while maintaining quietness performance.SOLUTION: There is provided a pneumatic tire with a sound controlling body. A sound controlling body 20 extends in at least a first tire axial direction T1 side from a tire equator C. A length A between an outer end 20a on the first tire axial direction T1 side of the sound controlling body 20, and the tire equator C is 0.7 time or more of a distance B between the tire equator C and a position X1 of a maximum ground length X. When the length A is 1.0 time or more of the distance B, a thickness Dx of the sound controlling body 20 at the position X1 of the maximum ground length X is smaller than a maximum thickness Dm of the sound controlling body 20.SELECTED DRAWING: Figure 1

    【課題】静粛性能を維持しつつ高速耐久性能を向上する。【解決手段】制音体付き空気入りタイヤである。制音体20は、タイヤ赤道Cから少なくとも第1タイヤ軸方向T1側に延びている。制音体20の第1タイヤ軸方向T1側の外端20aとタイヤ赤道Cとの間の長さAは、タイヤ赤道Cから最大接地長Xの位置X1までの距離Bの0.7倍以上である。長さAが距離Bの1.0倍以上の場合は、最大接地長Xの位置X1での制音体20の厚さDxが制音体20の最大厚さDmよりも小さい。【選択図】図1
