Abstract: A pneumatic tire tread has tread elements formed by circumferential and/or lateral grooves. At least one tread element has a sipe that devolves from a constant width sipe having a three dimensional aspect in at least a portion of the radially outer portion of the sipe to a wider width groove at the base of the tread feature.

Abstract: The present invention provides for an improved tire tread having an improved hydroplaning resistance. Specifically, the tread includes one or more tread blocks having one or more walls with an undercut surface to deviate the flow of water from a circumferential groove(s) to a lateral groove(s), thereby providing for improved worn hydroplaning performance of tires.

Abstract: Pneumatic tire with improved wear balance and improved handling performance under tire service conditions like loading, braking, and cornering. The tread of the pneumatic tire includes a radially outermost surface with at least first, second, and third regions defined between the tire's equatorial plane and the tire's shoulder. The second region is arranged coextensive with the third region to define a circumferential interface and the second region is tangent with the third region along the circumferential interface. A radius of curvature of the third region is less than a radius of curvature of the second region.
