Hello together, I wanted to get rid of my frustration and ask if anyone has it before. Last year in September I changed to HU not only the tyres but complete bikes, after that we hardly drove anymore. This year we were at the North Cape and had on the way to north Norway on a bad road stop. When we wanted to continue driving a friendly caravan driver came up to us and asked: “You already know that you have a record”? of course we haven’t yet, but at the Caravan left was Platt. So no problem, spare wheel on it and on. At the weekend arrived on the North Cape Island, we found a tyre service that promised us the reperforation to Monday. Really very nice and linguistic efforts. On Monday then the surprise, the tire was OK and according to service in a top condition. The rim is air-permeable on the welds that connect the rim star with the rim bed. So no repair. So we continue and over Ostschweden direction south. After one night stop in a parking lot then the surprise, Caravan on the right is Platt. SCHE….!!! We had unfortunately only a spare wheel with us. Locker 50km to the next bigger place, but a strawberry seller who just built a stand on the parking lot had the tip. A directions of about 6km, there was a tire service. So we both broken wheels into the tractor, disconnected and gone. The man from the service had indeed all employees We went to a small shop to buy groceries. Back at the service, the wheels were rolled out of the hall, two new rims had been purchased and assembled. Super service and that at the load and in the time. Back to the caravan, wheels under and on it went. During this holiday nothing had happened anymore, so as material defects of the rims were ticked and good. Now we were e a week in the Sauerland, (120km a track) and when I crank up the columns hit me the blow, caravan left flat. Reserve wheel on it and home. At home air on the tires and the water hose on it. Shock, the air comes from the rim. Although the rims come from two different countries, the same problem. Has anyone experienced similar things before? Greeting Manfred
