摘要： PROBLEM TO BE SOLVED: To provide a tire in which flat spotting is reduced. SOLUTION: The invention improves tire flat spotting by providing a bead assembly that has bead filler elements (34, 32) disposed outside the body cords so that the turn up portion (18) of body cords is disposed immediately back against the main portion (16) of the ply of body cords above the bead core (14). This carcass structure increases the stiffness of the lower sidewall and decreases the flat spotting experience by the tire. In one embodiment, a reinforcing ply (40) is wrapped around the bead filler elements to further increases the stiffness of the lower sidewall. In another embodiment, a bead filler element (34) is disposed inside the body cords so that an air pocket is not formed in the carcass during the manufacturing process. COPYRIGHT: (C)2011,JPO&INPIT
摘要翻译：要解决的问题：提供一种其中平坦点样减少的轮胎。解决方案：本发明通过提供一种胎圈组件来改善轮胎平均斑点，所述胎圈组件具有设置在身体帘线外部的胎圈填充元件（34,32），使得身体帘线的翻盖部分（18）紧靠着主体胎体帘线（14）上方的帘线帘布层的部分（16）。该胎体结构增加了下侧壁的刚度并且减小了轮胎的平均点样体验。在一个实施例中，加强层（40）缠绕在胎圈填充元件周围以进一步增加下侧壁的刚度。在另一个实施例中，胎圈填充元件（34）设置在主体帘线内部，使得在制造过程中不会在胎体中形成空气袋。版权所有（C）2011，JPO＆INPIT

摘要： A method for reducing vehicle bias when testing a tire for use with a market segment of vehicles by creating a vehicle model that is scalable by vehicle weight. A market segment of vehicles is defined, at least one of a vehicle model parameter is defined, data is collected for the at least one vehicle model parameter from at least one vehicle in the market segment, the at least one vehicle model parameter is characterized through regression analysis as a function of total weight of a scalable vehicle model, the scalable vehicle model parameter is applied to a multibody vehicle dynamics simulation, at least one maneuver is applied to the scalable vehicle model, and the tire load histories generated by the multibody vehicle dynamics simulation are provided to a tire test machine to obtain tire wear data representative of the vehicles in the market segment.

摘要： A tire includes a tread having a first plurality of tread blocks on a first side of an equatorial plane and a second plurality of tread blocks on the second side. Each of the first plurality of tread blocks has a first leading lug wall, a first trailing lug wall, a first leading sipe proximate to the first leading lug wall, and a first trailing sipe proximate to the first trailing lug wall. Each of the second plurality of tread blocks has a second leading lug wall, a second trailing lug wall, a second leading sipe proximate to the second leading lug wall, and a second trailing sipe proximate to the second trailing lug wall. The first leading sipes have a depth greater that of the first trailing sipes. The second leading sipes have a depth less than that of the second trailing sipes.
摘要翻译：轮胎包括胎面，该胎面具有在赤道面的第一侧上的第一多个胎面花纹块和在第二侧上的第二多个胎面花纹块。第一组多个胎面花纹块中的每一个都具有第一前凸耳壁，第一后凸耳壁，靠近第一前凸耳壁的第一前切迹线以及靠近第一后凸耳壁的第一后切迹线。第二多个胎面花纹块中的每一个均具有第二前凸耳壁，第二后凸耳壁，靠近第二前凸耳壁的第二前轮胎花纹以及靠近第二后凸耳壁的第二后轮胎纹。第一条主要的刀槽花纹的深度大于第一条末端的刀槽花纹。第二条主导沟槽的深度小于第二条尾沟槽的深度。
