To provide a motor-cycle tire that is able to improve performance for pushing the vehicle with hands, without decreasing heat generation resistance performance.SOLUTION: A motor-cycle tire 100 includes: a pair of bead cores 3; a carcass layer 2 folded around each of a pair of bead cores 3 and from inside in a tire width direction to outside in the tire width direction, in a tire meridian cross-section and wound up to a side wall portion from inside in a tire radial direction to outside in the tire radial direction; a tread portion 5 provided outside the carcass layer 2 in the tire radial direction; and a reinforcement rubber layer 7 provided on a tire inner cavity side of the carcass layer 2. The reinforcement rubber layer 7 is located across a tire equatorial plane CL. In a cross-section along the tire equatorial plane CL, the reinforcement rubber layer 7 has an uneven shape formed of a recess and a projection, the projection has a long shape with short sides and long sides, and each long side extends in the direction of an angle of 46 degrees or more and 90 degrees or less relative to a tire circumferential direction.SELECTED DRAWING: Figure 1

    【課題】耐発熱性能を低下させずに、車両手押し性能を向上させることのできる自動二輪車用タイヤを提供する。【解決手段】自動二輪車用タイヤ100は、一対のビードコア3と、タイヤ子午断面において、一対のビードコア3それぞれの廻りにタイヤ幅方向内側からタイヤ幅方向外側に折り返され、かつ、タイヤ径方向内側からタイヤ径方向外側にサイドウォール部まで巻き上げられたカーカス層2と、カーカス層2のタイヤ径方向外側に設けられたトレッド部5と、カーカス層2のタイヤ内腔側に設けられた補強ゴム層7とを有する。補強ゴム層7は、タイヤ赤道面CLを跨ぐ位置に設けられている。タイヤ赤道面CLに沿った断面において、補強ゴム層7は、凹部と凸部とからなる凹凸形状を有し、凸部は、短辺と長辺とからなる長尺形状であり、長辺は、タイヤ周方向に対して46度以上90度以下の角度の方向に延在する。【選択図】図1
