Abstract: 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.

Abstract: 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 ph

Abstract: A lightweight truck and passenger vehicle tire having an improved tread design that provides numerous biting edges for increased grip in mud, snow, loose debris, and when climbing rocks as well as providing increased protection from punctures and cuts to the tire's shoulder and upper sidewall regions.
