Abstract: A pneumatic tire includes a pair of axially spaced apart annular bead cores, a carcass ply extending around both bead cores, a tread for engaging a contact surface and a belt structure. The tread has at least one circumferential groove extending radially inward from a radially outer surface of the tread. The belt structure includes at least one belt layer and an overlay comprising at least one overlay layer. The overlay layer is disposed under the circumferential groove and has an axial width between 70% and 200% of an axial width of the circumferential groove. The overlay layer is a reinforced ply layer or a layer comprising a fabric.

Abstract: The present invention relates to a pneumatic tire having a pair of spaced apart bead components, a connecting carcass between said bead components, and a rubber chafer positioned around at least a portion of each of said bead components and intended for contacting a rigid rim of a wheel, wherein said chafer comprises an outer skin layer intended for contacting the rigid rim and an inner core layer disposed radially inward of the skin layer.

Abstract: A tire has an axis of rotation. The tire includes two sidewalls extending radially outward and a tread disposed radially outward of the two sidewalls and interconnecting the two sidewalls. The tread includes a main portion comprising a first compound and a reinforcing structure comprising a second compound having reinforcing short fibers oriented between ?20 degrees to +20 degrees to a circumferential direction of the tread. The main portion of the tread includes at least one circumferential groove separating circumferential ribs. Each circumferential groove has two sides and a base therebetween. The reinforcing structure includes a layer of the second compound secured to the sides of each circumferential groove.
