    Abstract: A racing tire comprising a tread having a new tread thickness of no greater than about 0.375 inch. The tread defines a running surface that includes a first circumferential portion of a first rubber compound and a second circumferential portion of a second rubber compound situated adjacent one another. The first rubber compound has a greater stiffness than the second rubber compound so as to provide the tread with greater wear resistance along the first circumferential portion, and the second rubber compound provides the tread with greater traction along the second circumferential portion. The tread may be substantially free of a tread pattern. The second rubber compound may have a greater DIN abrasion value than the first rubber compound. The second rubber compound may have a higher tan delta at 100° C. and/or a higher J″ traction value than the first rubber compound.

    Abstract translation: 一种赛车轮胎，其包括具有不大于约0.375英寸的新胎面厚度的胎面。 胎面限定了包括第一橡胶混合物的第一周向部分和位于彼此相邻的第二橡胶混合物的第二周向部分的运行表面。 第一橡胶化合物具有比第二橡胶化合物更大的刚度，以便沿着第一周向部分提供胎面具有更大的耐磨性，并且第二橡胶化合物沿着第二圆周部分提供具有更大牵引力的胎面。 胎面可以基本上没有胎面花纹。 第二橡胶化合物可具有比第一橡胶化合物更大的DIN磨损值。 第二橡胶化合物在100℃下可具有较高的tanδ和/或比第一橡胶化合物具有更高的J“牵引值。
