TIRE WITH IMPROVED IRREGULAR WEAR PROPERTIES

摘要

TIRE WITH IMPROVED IRREGULAR WEAR PROPERTIES A directional tire tread which is resistant to irregular wear and optimizes noise properties of a tire, and methods of reducing noise characteristics of a tire are provided. The tread has lugs which are characterized by an open leading groove wall angle of 3.degree.-8.degree. and a trailing groove wall angle of 0.degree.-2.degree.. In a preferred embodiment, the leading edge of the lugs are rounded, and optionally the trailing edge of the lugs are rounded. In the illustrated embodiment the tread has arcuate lateral grooves. The methods relate to providing pneumatic tires with the above parameters.
