Air Pressure Gone Missing - Cause?

[Paul from Maine]

Remember you must exchange the winter air in your tubes for summer air each spring and replace the summer air with winter air each fall.

Sounds like me when I hallucinated for 3 1/2 weeks after taking Flexarill, a muscle relaxant, two years ago!!! Duh! Bill W.

If it's porous rubber in the tube, putting it in soapy water will do little good. To inflate a tube out of the tire takes only a couple of pounds or so, whereas in the tire you pump it up to 35# or so. The higher pressure will force air through the pores, unlike the 2 or 3 # used to test the tube out of the tire.
Nitrogen is a scam! As fast as you're losing air out of a defective tube, you won't see a difference with nitrogen. The molecules aren't that much bigger! I don't recall the exact numbers, but it's something like: if a good tire loses 2-3 lbs. a month, with nitrogen you only lose 1-2 lbs.

Ponder this when you go to bed: With all the developments in tires & tubes, our safety depends on that little tiny valve core also the 2 cotter keys in the front wheel bearing nuts!!
