<p>The present invention relates to a tire having a tire tread that includes: at least two grooves in a general circumferential direction; a plurality of transverse grooves (6), each transverse groove leading into two circumferential grooves via openings, the circumferential and transverse grooves having transverse sections suitable for enabling liquid on the road to flow while the wheels are turning; and a plurality of closing devices (7) located in said grooves, each closing device at least partially closing the transverse section of a groove, each closing device (7) defining, with a transverse groove end (6), a groove length from one half to three quarters of the length of an in contact circumferential groove and measured under nominal conditions for load and pressure. Said tire is characterized in that each closing device (7) is designed to bend and open the groove section in which the device is placed, being moved by a liquid flow so as to enable the flow of said liquid when the wheels are turning on a road covered with water.</p> |
