  Provided are a rubber composition, for a tire outer layer, that can improve low fuel consumption performance and ozone resistance in a balanced manner, and a pneumatic tire using the rubber composition. The rubber composition for the tire outer layer contains: a rubber component containing a butadiene rubber; a phenylenediamine antioxidant; and a surfactant having an HLB value of 5 to 12. The butadiene rubber contains a nitrogen atom and/or has a cis content of not greater than 60% by mass. An amount of the butadiene rubber in 100% by mass of the rubber component is 3 to 50% by mass. An amount of the phenylenediamine antioxidant is 1 to 10 parts by mass, an amount of the surfactant is 0.1 to 6 parts by mass, and an amount of carbon black is less than 25 parts by mass, per 100 parts by mass of the rubber component.

  本发明提供了一种用于轮胎外层的橡胶组合物，该组合物能够以平衡的方式提高低油耗性能和耐臭氧性，还提供了一种使用该橡胶组合物的充气轮胎。用于轮胎外层的橡胶组合物包含：含有丁二烯橡胶的橡胶成分；苯二胺抗氧化剂；以及 HLB 值为 5 至 12 的表面活性剂。丁二烯橡胶含有一个氮原子和/或顺式含量不大于 60%（按质量计）。丁二烯橡胶在 100%质量的橡胶组分中的含量为 3%至 50%。苯二胺抗氧化剂的用量为 1 至 10 份（按质量计），表面活性剂的用量为 0.1 至 6 份（按质量计），炭黑的用量小于 25 份（按质量计）。

  The present invention provides a rubber composition which has excellent processability owing to its low rubber viscosity during kneading, despite containing a white filler, and which further has excellent fuel economy and excellent abrasion resistance. Also provided is a pneumatic tire formed from the rubber composition. The present invention relates to a rubber composition including: a rubber component, a white filler, and a compound represented by the formula (1) below, wherein X represents —CONH— or —COO—; R1 represents a C7-C23 alkyl group or a C7-C23 alkenyl group; R2 represents a C1-C3 alkylene group; and R3 and R4 each independently represent a hydrogen atom, a C1-C3 alkyl group, or a C1-C3 hydroxyalkyl group, and at least one of R3 or R4 is the hydroxyalkyl group.

  本发明提供了一种橡胶组合物，尽管含有白色填料，但由于其在捏合过程中橡胶粘度较低，因此具有极佳的加工性能，而且还具有极佳的燃油经济性和出色的耐磨性。此外，还提供了一种由该橡胶组合物制成的充气轮胎。本发明涉及一种橡胶组合物，包括：橡胶组分、白色填料和下式（1）代表的化合物，其中 X 代表 -CONH- 或 -COO-；R1 代表 C7-C23 烷基或 C7-C23 烯基；R2 代表 C1-C3 亚烷基；R3 和 R4 各自独立地代表氢原子、C1-C3 烷基或 C1-C3 羟烷基，且 R3 或 R4 中至少有一个是羟烷基。
