The invention relates to pneumatic tires with a focus on pneumatic tires primarily intended for use in off-the-road service at relatively slow vehicular speeds, and to large
truck tires, aircraft tires and agricultural tires and therefor not primarily focused on, and in one aspect intended to be exclusive of, passenger tires and particularly smaller passenger tires, wherein the
elastomer composition of the treads, and at least two additional components, of such tires are of
natural rubber rich rubber compositions composed, based upon the elastomers of the rubber compositions, of at least 45, alternately at least 75 weight percent cis 1,4-polyisoprene
natural rubber. For this invention, the
natural rubber rich treads and at least two additional natural rubber rich rubber components of such tires contain rubber reinforcing carbon blacks comprised primarily of high reinforcing,
small particle size, carbon blacks. Silica reinforcement can also be used in combination with the high reinforcing
carbon black for the natural rubber rich tire components.
