TIRE HAVING TREAD GROOVES FORMING DOUBLE NETWORK OF CONTINUOUS CURVES

摘要

A tire has a tread formed with circumferential grooves following curves that are broken or undulating. The amplitudes of the curves increase in a direction from one edge towards the other edge of the tread. Over more than half the width of the tread, the curves followed by the grooves are substantially in phase opposition, and the grooves are connected to each other in such a manner that segments of one groove lie substantially in extensions of segments of an adjacent groove.
