    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。

    Abstract: This invention relates to a tire with a tread of a rubber composition which contains zinc rosinate within and on the surface of said rubber composition. Said zinc rosinate promotes enhanced wet traction for said tire tread by actually replacing a more conventional zinc stearate for a tire tread rubber composition. Said zinc rosinate is a product of a combination of rosin acid and zinc oxide formed in situ within said rubber composition. Said more conventional zinc stearate is a product of a combination of stearic acid and zinc oxide formed in situ within a tread rubber composition.

    Abstract translation: 本发明涉及一种具有橡胶组合物的胎面的轮胎，该橡胶组合物在所述橡胶组合物的表面内和表面上含有松脂酸锌。 所述松脂酸锌通过实际代替用于轮胎胎面橡胶组合物的更常规的硬脂酸锌来促进所述轮胎胎面的增强的湿牵引力。 所述松脂酸锌是在所述橡胶组合物中原位形成的松香酸和氧化锌的组合的产物。 所述更常规的硬脂酸锌是在胎面橡胶组合物内原位形成的硬脂酸和氧化锌的组合的产物。
