Hello dear SAABunity, I don’t get smart about the following thing at the moment: I drove 195 winter tires until last weekend. On the weekend I mounted 215 summer tires and since then have a buzzing while driving. Just before the traffic light (i.e. at a steady pace) it gets quite violent short, so that the turn signal lever ratters. What is that? That it rolls quite loud, I have already thought before. But after the tyre change it became my opinion much too loud. I thought I would have put the tyres on in the wrong direction of the race, but they are not available at all with these tyres, but only the indication of an outside. For information: these are Michelin Primacy. Can anyone help me?
