Abstract: A tire for vehicle wheels provided with a tread pattern includes at least one continuous central circumferential groove straddling an equatorial plane of the tire, at least two continuous lateral circumferential grooves having median planes substantially parallel to the equatorial plane of the tire, and a plurality of transverse grooves. These grooves delimit at least four circumferential rows of blocks, two central rows and two shoulder rows. Each block of the central rows is defined by a plurality of sides and at least four vertices, a pair of front vertices and a pair of rear vertices, in relation to a predetermined running direction of the tire. The blocks of the central rows include a first transverse notch having a first terminal end inside a respective block of the central rows and a first starting end communicating with the at least one central circumferential groove.

Abstract: A pneumatic tire in which a sipe, which is substantially parallel to a contour line of a trailing edge of a ground-contact configuration, is formed in a trailing edge region of each block at shoulder sides of the pneumatic tire. From a time of step-in to a time of kick-out of a block, the effect of shearing strain which is transmitted to a trailing edge from a preceding trailing edge portion is mitigated, and movement of the trailing edge of the block with respect to a road surface is suppressed. Accordingly, wear at the trailing edge of the block, i.e., heel-and-toe wear, is suppressed, and noise caused by heel-and-toe wear is reduced.

Abstract: Vehicle tire and a metal sheet mold plate for forming the vehicle tire having at least one axial end section includes a tread that includes sipes running substantially axially in at least one of the axial end sections when viewed from the top (i.e., perpendicular to the tread surface). The sipes are corrugated to form corrugated ridges and valleys that are substantially straight lines diagonally inclined in an oblique plane parallel to the substantially axially running sipes. The substantially axially running sipes may include a first set of sipes and a second set of sipes. The corrugated ridges and valleys of the first set of sipes are oriented, with regard to a radially outward direction, to extend axially inwardly toward (i.e., toward a axial center of the tire). Conversely, the corrugated ridges and valleys of the second set of sipes are oriented, with regard to the radially outward direction, to extend axially outwardly (i.e., away from the axial center of the tire). At least one joint track is also provided that includes the corrugated sipes of the first and second sets of sipes.
