PROBLEM TO BE SOLVED: To provide a rebuilt tire capable of improving wet performance.SOLUTION: A rebuilt tire 10 is configured so that a tread 20 comprises: at least three peripheral main grooves 21, 22 extending in a tire peripheral direction; and plural land parts 31, 32 formed by being divided by these peripheral main grooves 21, 22 on a tread surface. In addition, a tread width TW and a tire total width SW satisfy the relationship of 0.65≤TW/SW≤0.85. In addition, a distance SDH from a rim diameter measurement point P to a tire maximum width position Q in a tire radial direction and a tire cross section height SH satisfy the relationship of 0.45≤SDH/SH≤0.65. The land part 31 on the inside of the tire width direction, adjacent to the outermost peripheral main groove 22 has one peripheral narrow groove 311 continuously extending over tire whole periphery.

    【課題】ウェット性能を向上できる更生タイヤを提供すること。【解決手段】この更生タイヤ10では、トレッド20が、タイヤ周方向に延在する少なくとも3本の周方向主溝21、22と、これらの周方向主溝21、22に区画されて成る複数の陸部31、32とをトレッド面に備える。また、トレッド幅TWと、タイヤ総幅SWとが、0.65≰TW/SW≰0.85の関係を有する。また、リム径の測定点Pからタイヤ最大幅位置Qまでのタイヤ径方向の距離SDHと、タイヤ断面高さSHとが、0.45≰SDH/SH≰0.65の関係を有する。また、最外周方向主溝22に隣接するタイヤ幅方向内側の陸部31が、タイヤ全周に渡って連続的に延在する1本の周方向細溝311を備える。【選択図】図3
