Provided are: a rubber material for tires, which has an excellent balance among wear resistance, low fuel consumption, and wet grip; a master batch and a rubber composition for tires, which are suitable for the production of the rubber material for tires; a method for producing the master batch and the rubber composition for tires; and a tire comprising a tire member formed from the rubber material for tires. A rubber material for tires, which contains 5-90 parts by mass (inclusive) of a hydrophilic fumed silica and 1.5-30 parts by mass (inclusive) of a silane coupling agent per 100 parts by mass of a total rubber component comprising at least one selected from the group consisting of natural rubbers and synthetic rubbers, in the rubber material for tires, the stress at 100% elongation (M100: MPa), the tensile breaking strength (TB: MPa), and the tensile breaking elongation (EB:%) of the rubber material for tires satisfy the following relationship. TB * EB/M100 is greater than or equal to 4000 and less than or equal to

    本发明提供耐磨耗性、低油耗性以及湿抓地性的平衡优异的轮胎用橡胶材料、适于轮胎用橡胶材料的制造的母料和轮胎用橡胶组合物、母料和轮胎用橡胶组合物的制造方法以及包含由该轮胎用橡胶材料形成的轮胎构件的轮胎。一种轮胎用橡胶材料,其中,相对于由选自由天然橡胶和合成橡胶组成的组中的至少一种构成的总橡胶成分100质量份,包含5质量份以上且90质量份以下的亲水性气相二氧化硅、以及1.5质量份以上且30质量份以下的硅烷偶联剂,在所述轮胎用橡胶材料中,轮胎用橡胶材料的伸长100%时应力(M100:MPa)、拉伸断裂强度(TB:MPa)以及拉伸断裂伸长率(EB:%)满足下述的关系。4000≤TB×EB/M100≤13000。
