    摘要： The invention relates to a tire having a lug and groove configured rubber tread having an outer rubber cap layer with a running surface and an underlying specialized transition rubber layer. The transition layer rubber is specialized in a sense of containing corncob granules. In one embodiment, the transition layer rubber may also contain at least one of partially depolymerized rubber, particulate pre-cured rubber and coal dust. The outer tread cap layer is comprised of ground-contacting tread lugs with the tread running surface and associated tread grooves positioned between said tread lugs. The tread grooves may extend radially inward through the outer tread cap layer and into the transition tread layer. The rubber tread configuration may also optionally also include a tread base rubber layer underlying the transition rubber layer. The corncob granules may be colored with a suitable colorant of non-black color so that the transition rubber layer might be used as a treadwear indicator (or tread depth indicator), depending somewhat upon the thickness of the transition rubber layer.

    摘要翻译： 本发明涉及一种具有凸耳和凹槽的轮胎，所述轮胎和凹槽配置有橡胶胎面，其具有带有运行表面的外部橡胶盖层和下面的特殊过渡橡胶层。 过渡层橡胶专门用于含有玉米芯颗粒的感觉。 在一个实施方案中，过渡层橡胶还可以包含部分解聚的橡胶，颗粒预固化橡胶和煤粉中的至少一种。 外胎面覆盖层包括具有踏面运动表面的接地接触胎面凸块和位于所述胎面凸耳之间的相关联的胎面花纹沟。 胎面槽可以径向向内延伸穿过外胎冠层并进入过渡胎面层。 橡胶胎面构造也可任选地还包括位于过渡橡胶层下面的胎面基底橡胶层。 玉米芯颗粒可以用合适的非黑色着色剂着色，使得过渡橡胶层可以用作胎面指示剂（或胎面深度指示剂），这取决于过渡橡胶层的厚度。
