Tire

The present invention is directed to a pneumatic tire, comprising at least one pair of parallel annular beads; at least one carcass ply wrappedaround said beads; a tread; and first and second sidewallsdisposed between said treadand one of said at least one pair of beads. In accordance with an embodiment of the invention, the tread comprises tread blocksand/or tread ribs, wherein the tread blocksand/or tread ribscomprise sipesextending essentially in an axial direction A of the tire, the sipesconsisting of an upper portionessentially aligned with the radial direction R of the tire and a lower portioninclined in the direction of rotation D of the tire

Pneumatic tire

Pneumatic tire with tread having sipes

A pneumatic radial ply tire for heavier load conditions having a reduced weight, high durability bead area. The pneumatic tire includes a tire bead and a carcass ply folded about the bead to define a main body portion and a turnup portion. The turnup portion is folded around the bead and located adjacent the main body portion radially outward of the bead. The turnup portion has a turnup height of approximately 35-45% of the total section height. A thin rubber strip associated with the bead is disposed between the main body portion and the turnup portion and has an insert height of approximately 25% of the total section height. The pneumatic tire further includes a chafer having a maximum chafer gauge of not more than approximately 1.5 times the thickness of the tire side wall.

Tire tread

A pneumatic tire with a shoulder rib and lateral grooves defined in a shoulder rib. A tread and shoulder of the tire are joined along a shoulder edge. The tread includes a circumferential groove defining the shoulder rib, which is adjacent to the tire's shoulder. The lateral grooves, which intersect the shoulder edge, extend laterally across the shoulder rib, but do not intersect the circumferential groove.
