PROBLEM TO BE SOLVED: To provide a tire capable of suppressing groove deformation of a tread during tire operation.SOLUTION: A tire tread 10 includes: a plurality of circumferential grooves 20 separating circumferential ribs, each groove including a bottom 21 and two sidewalls 22 and 23; and one or more groove reinforcements 30 and 31, each groove reinforcement laterally spaced from any other of the one or more groove reinforcements. Each groove reinforcement is arranged adjacent to one circumferential groove, and at least one circumferential groove has no groove reinforcement adjacent thereto. Each groove reinforcement also extends from a radially inner surface 36a of the tread in a radially outward direction 36b to at least the bottom of the adjacent circumferential groove, and at least part of the bottom of the groove is formed on the tread.SELECTED DRAWING: Figure 1

    【課題】タイヤの動作中のトレッドの溝変形を抑制したタイヤの提供。【解決手段】周方向リブを分離している複数の周方向溝20と、ここで各溝は底部21と二つの側壁22&23を含み、一つ又は複数の溝補強材30&31は、各溝補強材が、他の一つ又は複数の溝補強材から横方向に間隔をあけて配置されている溝補強材と、を含むタイヤトレッド10であって、各溝補強材は一つの周方向溝に隣接して配置され、少なくとも一つの周方向溝が隣接する溝補強材を持たず、そして各溝補強材がトレッドの半径方向内面36aから半径方向外36b側の方向に、隣接する周方向溝の少なくとも底部にまで延び、その溝の底部の少なくとも一部を形成しているトレッドを含むタイヤ。【選択図】図1
