Abstract
A tire tread and a tire including a tread when the tread width is divided into circumferentially extending ribs by two or more circumferential grooves and at least one rib is subdivided into tread elements by transversely extending slots. The grooves are such that they close in the contact patch to resist movement between the tread elements and the slots provide water holding capacity for wet road use.
