<p>Tire tread provided with circumferential grooves delimiting two edge rows provided with a plurality of transverse grooves, those of one edge row forming at least one bearing block protruding on at least one delimiting wall, each comprising a surface capable of coming into contact with another surface during contact with the ground and at least one passageway for a fluid between each bearing block of a groove and the bottom of the groove. For each edge row, the mean surface indentation ratio Tc is at least 0.7 and at most 1.6 times E/R, where E is the mean thickness for all grooves comprising active surfaces measured between a radially outermost point of the active surface and a radially outermost point of the reinforcing belt, R is the mean distance for all transverse grooves comprising active surfaces measured between the point of the active surface that is radially outermost and the rotation axis of the tire provided with the tread.</p> |
