Hi there. Ride a new Seat Leon TDI 2.0 with 184hp since the beginning of this week. Have Continental Sport Contact 5 with 225 / 18 40 on it. The tires are so loud.From a speed of about 60 k/mh the tires roar that is really Wahsinn. Much louder than winter tires really sucking. Does any of you have the same experiences ?
