    摘要: This invention relates to tires having a tread of a natural rubber-rich rubber composition reinforced with a combination of rubber reinforcing carbon black and precipitated silica in which carbon black is in the majority of such reinforcement. In one aspect, the tread rubber has a balance of physical properties. Such balance of physical properties includes relatively high hardness and abrasion resistance properties balanced with an acceptable rebound property.
