摘要： An improved truck racing tire includes three belts and reduced tread and undertread thickness for weight reduction. An asymmetric shoulder design is provided and circumferential grooves having wear indicia therein at a preselected depth are incorporated into the tread to divide the tread into plural ribs. Notches are formed within the tread ribs in circumferential patterns of distribution at a depth equivalent to the depth of groove tread wear indicators. The tread is constructed of a relatively softer compound in the cap and a relatively harder compound in the base. The boundary between the cap and the base is at a depth corresponding to the notch depth and the wear indicators within the grooves to provide a further indication and confirmation of wear pattern and magnitude.

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.
