Passenger vehicle tire, the tread having edge parts (11), provided with a plurality of transversely or obliquely oriented cuts (3) having a width at most equal to 2 mm and a depth at least equal to 75% of the thickness of the tread that is intended to be worn away, more than half of the cuts (3) comprising a protuberance that locally reduces the width of the cut (3) to a width at least equal to 0.2 mm and at most equal to 0.5 mm. The tread material which comes into contact with the road surface in the new state has a Shore A hardness at least equal to 48 and at most equal to 57, a loss at 60° C. at least equal to 12% and at most equal to 20%, a glass transition temperature Tg at least equal to −20° C. and at most equal to −10° C.
