A truck steer tire, a mold and a method of molding

摘要

A truck steer tire (10) has a side groove (24, 240) that extends laterally inwardly from a treadwall (29) in a circumferentially continuous fashion. The side groove (24, 240) lies between the tread surface (26) and a belt reinforcing structure (15). The side groove (24, 240) has a minimum groove (w) of 5 mm or greater and a groove depth to width ratio of 1.0 to 2.4. The side groove (24, 240) preferably has a groove base (24A) having a radiused profile (R), the radially inner portion of the radiused profile (R) being at least equal to one-half the minimum groove width (w).
