Abstract: The rubber composition for chafer is characterized in that 55-75 parts by weight of carbon black having a nitrogen adsorption specific surface area of 70-120 m2/g and 0.2-0.5 parts by weight of 1, 3-bis (citraconimidomethyl) benzene are blended with respect to 100 parts by weight of a rubber component including 30-50 parts by weight of natural rubber and/or polyisoprene rubber and 50-70 parts by weight of polybutadiene rubber. The pneumatic tire utilizing the chafer rubber composition is excellent in creep resistance, toe-cracking resistance, rim-slippage resistance of a bead portion through its lifetime from the beginning to the end of running, and durability of the bead portion. In the case of a tubeless tire, it also exhibits good air-tightness, thereby ensuring retention of the internal pressure.

Abstract: A radial ply pneumatic tire (10) features a bead core (20) which comprises an arrangement of filaments (26) positioned relative to one another. The bead core (20) has a cross-section and a radially inward base side (44), a radially outermost side (46), an axially inward first side (48), and an axially outward second side (50). In the cross section, the base side (44) of the bead core (20) has a width which is substantially linear and is between 50% to 75% of the rim seat width. The bead core base side (44) is inclined at least 15null relative to the bead's axis of rotation, while the bead heel surface has an as molded inclination at the central portion (61) radially inward of the bead base (44) at an angle of at least 10null with respect to the bead's axis. An associated rim (22) has a pair of humps (80) and a rim flange (76) associated with each hump (80). Each rim flange (76) has an axially inward surface (74), the distance between each hump (80) and the axially inward surface (74) of the associated rim flange (76) being a rim seat (62). The tire (10) further has a unique toeguard chafer (66) compound that is cut resistant.

Abstract: 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.

Abstract translation: 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，可以将uintraite加入到用于胎面（包括底座和盖子），侧壁，顶点，胎圈包布，胎圈涂层，护垫，衬里，帘布层，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，其由大致环形的胎体组成，外周胎面适于与地面接触，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 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。
