摘要： The invention provides a method for balancing tire performance with both increased and decreased numbers of lugs on the ribs while also having desirable tire noise performance. This method allows the tire designer to take advantage of the benefits of both high and low pitch count patterns while minimizing undesirable tire noise. The method involves the design of the fundamental pitch of the tire tread pattern and the design of the tread pattern for the tire. The invention also provides tires incorporating the fundamental pitch and tread patterns.
