Tire tread having serrated grooves |
摘要 |
<p>A tread for a tire comprising a plurality of elongate groove fingers (24A, 24B) is disclosed. At least two of said elongate groove fingers (24A, 24B) are connected by at least one channel (60) extending along a longitudinal axis and connecting at opposite ends to the elongate groove fingers (24A, 24B) The channel (60) is submerged from a radially outward tread surface (62) and has a longitudinal centerline plane and a pair of spaced apart channel sidewalls (74, 76) extending to a channel base surface (78). The tread (16) further comprises first and second arrays (44, 46) of serrations lining a respective longitudinal side of the channel (60), each serration extending into the tread surface (62) and comprising inward tapering serration sidewalls (50, 52) extending to a serration base surface (56). The serrations extend to intersect the centerline plane of the channel (60) at an intersection angle in a range of from 80° to 100°.</p> |
