Pneumatic tire

摘要

A pneumatic tire (10) has a tread (12) having a plurality of grooves (16) creating an initial tread configuration. The grooves and the tread elements formed thereby result in a tread have a net-to-gross ratio in the range of greater than 60%. Due to variations in the depths and variations in the heights and formations of the tread elements, after the tread has been worn, the tread has a net-to-gross ratio in the range of less than 60%.
