[QUOTE="Texas John, post: 122005, member: 3367"] In one case for a tire sitting in my garage for a bike I am working on, I used a new (Maxim?) HD MX tube which lost 3-4 PSI per month which I tracked (date and PSI on a note) over a number of months. I changed the tube to an XHD one with same experience. No miles or weight were put on the tire. Yes, I am aware that temp can affect PSI but going from Jan to July there is not too great a temp spread in my garage (but on a warming trend) to account for the steady loss. I also replaced valve cores with new genuine Schrader cores which made no difference. Either it is the tubes or the metal valve stems are no longer made exactly right for cores to seal against them properly (something I have no way to test for or verify). I will probably replace it with something else when I am ready to use this bike, but not sure what at this point which is why I am looking for feedback from anyone who has had a recent good experience that they actually verified the air-holding ability of their tube(s).
