摘要：
A pneumatic tire has a tread; the tread has a plurality of grooves, 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%.
