    摘要: A pneumatic radial tire having a circumferentially extending equatorial plane of the tire, the tire comprising a carcass, a tread radially outward of the carcass, the carcass comprising at least one carcass reinforcing ply, opposing bead portions, and opposing sidewalls, the carcass reinforcing ply having a main portion extending between the opposing bead portions and a pair of turnup portions, each turnup portion extending from one end of the main portion, each bead portion having a bead core, and a reinforcement cavity outward of each bead core, the cavity located between the main portion and one turnup portion of the at least one reinforcing ply, the tire characterized by: the tread comprising a radially outer tread cap and a radially inner tread base radially underneath the tread cap, the tread base comprising a rubber composition comprising from 15 to 45 phr of styrene-butadiene rubber; from 20 to 50 phr of polybutadiene; and from 10 to 35 phr of natural or synthetic polyisoprene, and from 35 to 65 phr of carbon black, wherein the rolling resistance of the tire is from 1 to 10 percent lower that for an otherwise identical tire not including the tread base.

    摘要: A pneumatic radial tire has a chipper in place of a traditional apex, the chipper located between a carcass main portion and turnup portion. The chipper layer may be composed of a chopped carbon fiber and aramid composite reinforced elastomeric layer. The tire sidewalls have a radial height SH and a section width SW located within a range of 0.4 to 0.44 of the sidewall radial height SH measured from the bead core. The section width SW may further be located within a range of 0.1″ to 0.3″ inches from a radially outward end of the chipper layer in a radial direction. The tread may of a dual layer construction, having a radially inward first layer formed of a relatively low rolling resistance compound and a radially outward second layer formed of a compound containing silica.
