PROBLEM TO BE SOLVED: To provide a tire improved so as to prevent heat from being accumulated in the tire and allow a vehicle to travel at a lower temperature.SOLUTION: A tire 10 for heavy loads according to the invention has a tread 12 positioned outside in a radial direction of a carcass. The tread 12 has a plurality of lugs extended from inside to outside in the radial direction and positioned between a first lateral edge part 13 and a second lateral edge part 14 of the tread 12. Lugs 30 constituting a first row extend toward a center surface of the tread 12, from the lateral edge part 13 toward inside in a shaft line direction, and lugs 40 constituting a second row extend toward the center surface of the tread 12, from the lateral edge part 14 at the opposite side of the lateral edge part 13 toward inside in the shaft line direction. The lugs 30 and 40 are separated by a plurality of shoulder grooves 22 and 24, the row of the lugs 30 is aligned to the row of the lugs 40, and a center row of lugs 50 is positioned between the lugs 60 and the lugs 70 which are offset. All lugs of each row are aligned in a circumferential direction.SELECTED DRAWING: Figure 1

    【課題】タイヤに熱が蓄積されにくく、より低い温度で走行するように改良されたタイヤを提供する。【解決手段】本発明に係る重荷重用タイヤ10は、カーカスの半径方向外側に位置するトレッド12を有する。トレッド12は、内側から半径方向外側に延び、トレッド12の第1の横縁部13と第2の横縁部14の間に位置する複数のラグを有する。第1の列をなすラグ30が、横縁部13から軸線方向内側へトレッド12の中央面に向かって延び、第2の列をなすラグ40が、横縁部13とは反対側の横縁部14から軸線方向内側へトレッド12の中央面に向かって延びている。ラグ30,40は、複数のショルダー溝22,24によって分離され、ラグ30の列はラグ40の列に位置合わせされており、中央のラグ50の列はオフセットされたラグ60とラグ70との間に位置する。各列の全てのラグは、周方向に位置合わせされている。【選択図】図1
