Abstract
A tire tread comprising at least one groove that is delimited by two opposing walls that are connected by a groove bottom. The groove has a width and a depth and at least one resonance-noise-reducing device. The device is formed of at least one blade that is fixed to one of the walls delimiting the groove or to the groove bottom and at least partially closes the cross section of the groove. The each flexible blade comprises two main walls which close the cross section of the groove. End walls delimit the main walls and a connecting wall connecting to the tread. Each blade further comprises at least one raised rib on at least one of its main walls, and the raised rib starts from the wall or the bottom bearing the blade and extends over at least 50% of the length of the flexible blade.
