Abstract
The tire has a tread with a tread surface and at least one groove which has a bottom wall and two lateral walls. At least one flexible wall is arranged in the groove in such a way that as liquid flows, the flexible wall flexes to allow the liquid to pass. After molding, the tire has a connecting element with a thickness which is equal to that of the bottom wall so that, after vulcanizing, the connecting element connects the lateral walls to the bottom wall over a given depth. The connecting element is then cut at its junction with each of the lateral walls of the groove so as to obtain the flexible wall.
