PNEUMATIC TIRE

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...

Zusammenfassung: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.
