after I bolted the winter tires to the IX today I had noises and vibrations in the drive as if I were driving on cobblestones. When rolling the noises and vibrations were gone. The phenomenon occurred between 20 and 90 km/h. The tires were already on it last year. Only difference, I made the rears to the front, because these have more profile (about 3mm more) After I changed the tires from the rear to the front were the phan Does anyone have an explanation for this?
