Hello guys, I just came from the workshop and just have to ask you …. the following facts. Three – four weeks ago I bought new tyres and had them pulled up by a workshop on my rims. This morning arrived at the vehicle three of my four tyres were visibly flat (car stood for a week in the parking lot). Then drove to the workshop (approx. 500 m) and received the notification that all four metal valves are broken. The replacement of the valve If a valve had been broken, I wouldn’t have had a problem with the whole thing. However, I find it very strange that all four valves would have broken at once. Would the workshop have had to check the metal valves in the case of new tyres? Is there any protection for me? What do you think about it?
