After I was allowed to find out that the left front tyre had expired considerably in the course of the change from summer to winter tyres (steel threads came to light and the tread was already partially detached), I decided to have the fall and the track adjusted. That’s how it happened. Feedback from the workshop, which also got to view the worn tire: There were considerable adjustments necessary. So far so good! Today, four days after the survey, I look for: e my wife with the car a workshop, because of noises from the front tire. The workshop found that the wheel was only so attached to the five wheel nuts. All wheel nuts were loose! After consultation in a large car dealership in Berlin, how fall and track is measured, I was told that the wheels were first dismantled to exclude mechanical damage (visibility test). Afterwards the tyres are mounted and measured. For setting is a demonstration With this knowledge I called the tyre company. Without reproach and without reproach, just stop the information. What can I say! The woman at the assumption knew immediately that the tyres were not dismantled and that I was to blame! A short conversation! Result: I control the tyres myself when I get the car out of the workshop! The customer is always to blame! The customer is always the fool!
