Hello, our Tourneo Connect Grand is equipped with all-year tires. 2 years ago we had new Hankook Kinergy 4 S on the rear axle. Since then we have driven about 25000 km. In the interior of the car there are now clearly unpleasant rolling noises. The tires are washed out and quite wavy. I drive with air pressure 2.6 bar, as the vehicle is never fully loaded, as stated. Is this normal on the vehicle? Is it possible to adjust the track at the rear somehow?
