Hello Phaetonauten, I have changed the direction of my 19″ Goodyear already for a long time rolling noise through sawtooth formation. In the spring I was finally tired and changed the wheels diagonally, so the direction of the running is changed. I know, you don’t actually do, there is increased wear and is not working on all tires. Goodyear is however not tied to the direction of the running. Result, nothing, stays so loud. No matter whether it gets better or the tires are flat, so what should. Now I had a wheel bearing damage at the rear left. It was fixed on guarantee with chassis measurement and adjustment. Result – totleise, you can whisper in the car and understand every word, wow. Now obviously the diagonally plugging has brought something, but was only “compensated” by the starting bearing damage, the rolling noises remained the same. In reality the tires became ever quieter and the wheel bearing became louder. I would do it in the fall, but they are bound to run. With this topic I don’t want to know anything about it.
