Abstract
The tire tread having a tread surface and a total thickness E and at least one main groove which opens when new onto a tread surface. In the vicinity of this main groove, at least one discontinuous secondary groove has a plurality of hidden parts and a plurality of open parts. The open parts are open onto the tread surface when new. The main groove and the discontinuous secondary groove have roughly identical main directions. The mean distance L, which is a distance measured at the open parts between the mean surface of the main groove and the mean surface of the discontinuous groove, is less than the mean distance Lmeasured between the mean surface of the main groove and the mean surface of the discontinuous groove in the regions of the discontinuous groove that do not have open parts.
