Tire with sipes of defined curvature

A tire has a tread, the tread having a plurality of ground engaging tread elements (10) creating a tread surface (26) and at least one of the elements has a sipe (12) therein. In planes parallel to the tread surface, the configuration of a radially outer portion of the sipe (12) is defined by a cont...

Beschreibung
Zusammenfassung:	A tire has a tread, the tread having a plurality of ground engaging tread elements (10) creating a tread surface (26) and at least one of the elements has a sipe (12) therein. In planes parallel to the tread surface, the configuration of a radially outer portion of the sipe (12) is defined by a continuous non-linear curvature, the curvature having at least one radius R. The value of the radius R of the sipe curvature increases from the tread surface (26) to a base (28) of the sipe (12) and the base (28) of the sipe has a configuration defined by a radius having a value of infinity.
