With me all car valves were not clean gripped so when inflating the hose always flaked off and inflating a Fahrradschaluches ordeal was.
The same thing happened at the Schrader valve tires our pushchair and the hand truck.
Only when car tires I had no problems, but I prefer to pump at the gas station.
My old stand-Baumarkt air pump I have now repaired, which had not made such a funny business.
