Hello, I just drove my car on a round trip through Scandinavia and have 4 new Nokia Hakkapelitta R3 on used steel rims on it. So I already drove about 1000km without any problems and all of a sudden the rdks reports a pressure loss of about 0.5 bar overnight when I am standing. I have already refilled, when driving there is no pressure loss. The tyre workshop here on site found no defect on the tire. Sometimes the valve changed, but nevertheless renewed pressure reliability What do I do best now?
