Hi guys.I just changed my tire to dunlop direzza 215/45/17 as i read sum very good reviews bot it on the net.Sadly after fixing it i realised it is much noisier than my prebious tires which were simex.A lot of road noise and on the highway it is irritating.Wat i dont understand is that the tire is from japan and if its noisy when its new,can u imagine the noise when its 30% worn out.Wat r ur opinions?Do u think the tires are defective or its suppose to be like that.Grip is excellent but maybe coz its new.By the way the speed rating is W
