Abstract

A design for a high-speed tire tread is provided that gives improved performance in both water and snow conditions. The tread region of the tire uses transversely-oriented grooves that each extend across the width of the tread region. There are no grooves or other tread features that provide substantial fluid communication between the transversely- oriented grooves. Features are also provided that decrease the pull under torque associated with such a design.

Description

technical field [0001] The present invention relates to a novel design of tread for high-speed tires that provides improved performance in water and snow conditions using transversely oriented grooves, each extending across the width of the tread area without grooves or Other features provide substantial fluid communication between such laterally oriented grooves, and relate more particularly to such designs with features that reduce the pull under torque associated with such designs. Background technique [0002] Road surfaces covered by rain or snow present challenges to tire designers. Rain on the road can cause the vehicle to suffer from hydroplaning, especially at higher speeds. Generally, hydroplaning occurs when a tire begins to push water in front of the tire as it travels along the road. Hydroplaning occurs when the pressure of the water pushing back on the tire is sufficient to lift the tire off the road and potentially cause vehicle control problems. The pressu...
