    • A tire manufacturing method includes a method for optimizing the uniformity of a tire by reducing the after cure radial force variation. The after cure radial force variation vector is modeled as a vector sum of each of the vectors representing contributions arising from the tire building steps—the “tire room effect vector” and a vector representing contributions arising from the vulcanization and uniformity measurement steps—the “curing room effect vector.” In further detail, both the tire room and curing room effect vectors can be further decomposed into sub-vectors representing each radial force variation contribution for which a measurable indicator is available. For a series of tires, the method obtains such measurements as the before cure radial runout (RRO) at one or more stages of the building sequence, measurements of loading angles on the tire building equipment, and measurements made during vulcanization process.
    • 轮胎制造方法包括通过减小固化后的径向力变化来优化轮胎的均匀性的方法。 后固化径向力变化矢量被建模为表示轮胎建造步骤产生的贡献的每个向量的矢量和 - “轮胎室效应矢量”和表示由硫化和均匀性测量步骤产生的贡献的矢量 - “ 养护室效应矢量“。 更详细地,轮胎室和固化室效应矢量可以进一步分解成表示可测量的指示符可用的每个径向力变化贡献的子向量。 对于一系列轮胎,该方法在建筑物顺序的一个或多个阶段获得诸如前固化径向跳动(RRO)的测量,轮胎建筑设备上的负载角度的测量以及硫化过程中的测量。
