PNEUMATIC TIRE TREAD

摘要

A pneumatic tire, which is capable of improving grip performance on road surfaces with low coefficients of friction, and further improving the durability of a tread pattern, is provided. This pneumatic tire tread (1) has a contact patch element (5) partitioned by grooves (4) (4a, 4b) that are formed on the tread. Small notches (3) are formed on the contact patch element, and each small notch has one arc section (33) and two ends (31, 32) formed on the contact patch surface of the tread at least when the tire is new. Furthermore, the small notches extend in such a manner as to open at a width (E) on the contact patch surface of the tread and not to open on the grooves, and the length (L) of the notches is not more than 3.0 mm.
