Tire tread including serrations in recessed pockets of groove sidewall

A tire comprising:

• first and second laterally spaced sides;
• and
• a tread interposed between the first and second sides, the tread including a tread surface having at least one groove therein, the at least one groove including facing, first and second sidewalls separated by a groove bottom surface, and a first pocket region of recessed serrations extending over at least a portion of the first sidewall and a second pocket region of recessed serrations extending over at least a portion of the second sidewall, the serrations of the first and second pocket regions being staggered in a circumferential direction relative to one another, wherein the serrations in a first pocket region decrease in height in the circumferential direction.
