    • This invention is based upon the unexpected discovery that uintahite can be incorporated into tire component rubber to improve the physical properties thereof. For example, by incorporating uintahite into tire tread rubber compositions, tires with improved tear and puncture resistance can be manufactured. Since uintahite is a relatively low cost material, its incorporation into tires also reduces cost. For instance, uintahite can be incorporated into a wide variety of tire rubber compounds used in the tread (including the base and the cap), sidewall, apex, chafer, bead coat, toeguard, innerliner, ply coat, gum strips, coverstrip, overlay and wedge stocks. This invention more specifically discloses a pneumatic tire which is comprised of a generally toroidal-shaped carcass, an outer circumferential tread which is adapted to be ground contacting, two spaced beads and two sidewalls extending radially from said spaced beads and connecting said tread to said spaced beads, wherein said tread is comprised of at least one rubbery polymer and from about 1 phr to about 20 phr of uintahite.
    • 本发明基于意外的发现,即将铝铁矿石掺入轮胎部件橡胶中以改善其物理性能。 例如,通过将uintraite合并到轮胎胎面橡胶组合物中,可以制造具有改善的抗撕裂性和耐穿刺性的轮胎。 由于uintraite是一种成本相对较低的材料,因此其并入轮胎也降低了成本。 例如,青蒿素可以掺入到用于胎面(包括基底和帽子),侧壁,顶点,胎圈包布,珠粒涂层,护垫,内衬,层层,胶条,盖带,覆盖层中的各种轮胎橡胶化合物中 和楔形股。 本发明更具体地公开了一种充气轮胎,其包括大致环形胎体,适于与地面接触的外圆周胎面,两个隔开的胎圈和从所述隔开的胎圈径向延伸的两个侧壁,并将所述胎面连接到所述间隔开的 珠粒,其中所述胎面由至少一种橡胶状聚合物和约1phr至约20phr的uintraite组成。
