研究降低295/75R22.5轮胎胎面胶滚动阻力的配方。设计2个低滚动阻力胎面胶配方：一个是主体材料为天然橡胶与顺丁橡胶和溶聚丁苯橡胶并用，炭黑用量为20份，白炭黑用量为34份；一个是主体材料为全天然橡胶，炭黑选用高耐磨炭黑，炭黑用量为30份，白炭黑用量为20份。结果表明，2个试验配方轮胎滚动阻力均明显降低，达到客户要求。

The purpose of this study was to reduce the rolling resistance of 295/75R22.5 tire by formulation design of the tread compound. Two formulations were designed. In one of the formulations, NR, BR and SSBR were selected as the base material, and the reinforcing system was 20 phr of carbon black and 34 phr of silica. In another one, base material was all NR, carbon black was a high abrasion furnace black and its addition level was 30 phr, and 20 phr of silica was also applied. The experimental test results showed that with either formulation, the tire rolling resistance was reduced signiifcantly, meeting customer requirements.
