If nobody else is going to address the elephant in the room, I guess I'll do it. For those of you who run brand new thin Asian-made tubes, do they very slowly and mysteriously lose air? Almost as if the air was somehow leeching out through the rubber?
In the antique car world, everyone is complaining about it, and I don't know whether it is real, imagined, or just a misidentification of the problem.
I am using new tubes in my bikes. I generally run at the maximum pressure listed on the tire. It is winter here, so most days are not bike days. After a few days sitting, I have never yet found the tires to be still up at maximum pressure. I have had to put more air in every single time. The tubes have valve caps on tight, so it probably isn't leaky valve cores. Maybe it was just tepmperature and weather changes?
Are any of you running Stan's sealer (or something similar) in your inner tubes? How did that work out?
