A tire has four circumferential grooves. Grooves are on the vehicle installation inner side of the tire, and on the vehicle installation outer side of the tire. Grooves which are on the vehicle installation inner side each have a plurality of fences in the groove arranged alternately along the groove next to each side wall of the groove. Grooves which are on the vehicle installation outer side do not have fences. The fences increase the path length of sound due to pipe resonance and delay the sound in comparison to grooves on the vehicle installation outer side of the tire. This directs the sound towards the inner side of the tire and reduces the noise on the outer side.
