如图15所示,通过比较在0℃拉伸状态下的tanδ值对湿路面牵引性能进行了预测,在此场合下其值越高最好。除了BR-丙烯酸酯三聚物外,使用新型填料的所有胶料其湿路面牵引性能预测值均比对比胶料出现了改善。使用硅烷醇填料和炭黑-白炭黑双相填料的胶料,则注意到其值较对比胶料的值大幅提高。同样,60℃下的tanδ值被用作预测胎面胶料滚动阻力的工具。在这种场合,此温度下的tanδ值较低则轮胎滚动阻力较小。根据图16中的结 As shown in FIG. 15, the wet traction performance was predicted by comparing the tan δ values ​​at 0 ° C in the stretched state, and in this case, the higher the value, the better. With the exception of the BR-acrylate trimer, all of the compounds using the novel filler showed improved wet traction performance over the comparative compound. Using a silanol filler and a carbon black-silica double-phase filler, it is noted that the value is significantly higher than that of the comparative rubber. Also, the tan δ value at 60 ° C. is used as a tool for predicting the rolling resistance of the tread stock. In this case, a lower value of tan δ at this temperature results in less rolling resistance of the tire. According to the knot in FIG. 16
