PROBLEM TO BE SOLVED: To inhibit buckling to reduce abrasion wear and improve grip performance.SOLUTION: In a tire 1 for a racing cart including a carcass 6 having a bias structure, a tread part 2 includes a side rigidity reinforcement member 9, which is made of rubber having higher modulus than tread rubber G0 disposed in a crown area YC, at a first shoulder area YS1 that is located at one side in a tire axial direction and includes a grounding property improvement member 10, which is made of rubber having lower modulus than the tread rubber G0 disposed in the crown area YC, at a second shoulder area YS2 that is located at the other side in the tire axial direction.SELECTED DRAWING: Figure 1
【課題】 バックリングを抑えてアブレージョン摩耗を減じるとともに、グリップ性能を向上させる。【解決手段】 バイアス構造のカーカス6を具えたレーシングカート用タイヤ1において、トレッド部2は、タイヤ軸方向一方側となる第1のショルダー領域YS1に、クラウン領域YCに配されるトレッドゴムG0より高モジュラスのゴムからなる横剛性補強部材9を具え、かつタイヤ軸方向他方側となる第2のショルダー領域YS2に、クラウン領域YCに配されるトレッドゴムG0より低モジュラスのゴムからなる接地性向上部材10を具える。【選択図】図1
