Hi together, a few weeks ago I got my winter tires on it. While I was on my way to a customer, I noticed from 100/110km/h that my steering wheel began to vibrate. Suspicion: tires not balanced. Unfortunately, I could not cancel the appointment with the customer so I had to drive a total of 800km. On the way back I noticed that the vibrations somehow decreased but the suspension felt every fugue and every hubbel let through into the body. The next day, I went to the workshop for testing the chassis (my vehicle still has a guarantee). There, nothing was found. Statements such as: subjective impression, too high air pressure, the change from summer to winter tires…. etc. “Stand der Technik”
