Hi, since 17.12.08 I have a little scumbag that screws out the valve inserts 2 times and leaves the air out for me. Now on Friday three tires Platt, only HR not. Simply flat, valve is complete and also not loosened. So tires pumped up. The next day again the same tires Platt. Pumped again. Driven to the gas station and set the correct air pressure. Test drive made and after 15min. again air pressure tested. Was less than 1bar on it. There is a small hole (not to be seen) on the tyre flank. Since for a few months the Tüv has expired (had neither time nor money to take care of it) my car was standing on a parking deck in a private place. However, in the middle of the dark. Since everyone can make a move on it without being seen. So I parked it on the road yesterday evening, as there the The left (who has the hole) is the only one who still has air. I have lubricated some fat on the hole, but that won’t keep it close. To all this I have a ticket to the windshield this morning, of course. 25€ due to an oversized tuv. My father immediately said that this is not a coincidence. There is some dirt dust in the back. Probably waiting for me to put my car on the road. Long speech… my question is now there can somehow come a small hole in the tire without someone stabbing through it with a needle? Somehow? Do you even come through the tire with a needle or something like that?
