Hello, I had my winter tires mounted around the corner last week in a small free workshop. I then drove 600 m home. Today, 600 m to the expressway (Tempo 80) and then after 10 km I had a knock and ratters in the city. Had just passed a construction site and thought the noise was coming from there. But the noise remained and I kept, engine lids open and listen, at the Mhd you are suspicious. From there it did not come. Next thought, the wheels and that was it then too. The rear left wheel has already wobbled while standing. I then called the ACE (thanks to the helper) and this then the only hand-fixed bolts have been tightened properly. He also had to pull the remaining three wheels, but they were solalala.Question: can be a damage to the braking system now and next question, I should report the workshop, because nothing happened and I did not land on the control plank or the next truck, finally only prevented my protection gel (here also thanks to the master supervision).
