Doh!
 
Valve stems would bleed out even if the cap was on as opposed to valve stem issues that would cause that hissing noise you mentioned. There could be a couple of things causing the core to leak,one being the core is not fully screwed in, the other being a piece of debris that is not letting the Schrader valve seat as designed, ie: sand or dirt?
 
Thanks! Since I have a ViAir compressor along with me I'll not try to fix it unless I have an extremely unlikely emergency. The remainder of our trip is on paved roads so I don't expect any issues. And I can see it being a core issue possibly exacerbated by my constant fussing with having the absolutely correct PSI (the magic 42) per gaijin. ;-)
 
Good illustration of how important those pesky caps are. I prefer caps that have a seal in the top vs the El Cheapo plain plastic ones. It's kinda scary to think that anyone of the 4 Schrader valves, that cost about a buck apiece, could ruin or stop a perfectly good trip. I carry 4 or 5 and a valve stem tool in my kit.

If you replace the valve core, will that cause the tire to break the bead? If so, then how do you reset the bead while out on the trail?

You have a good point about the caps -- they help in case of a leaking valve core.

If you go by an auto parts store, they will have a tire valve tool for about $5. Really easy to tighten the valve -- just put the tool on the valve core and gently tighten clockwise.

I think it's righty-tighty, lefty-loosey? It's possible to remove and replace said valve without loosing all the air in tire and in all probability the bead won't be broken if all of the air excapes. This is one of those tasks that can be practiced at home on any mounted tire from a wheel barrow to a bike to your car or spare tire. Unscrew existing valve (it will shoot out if you don't hold it in place on tool) put a finger over valve stem place new valve in tool, reinstall new valve. Sure some air will leak out but it conserves the majority.
 
I apologize for hijacking this thread. But this is very helpful and informative to me!

Okay, I feel guilty asking @gaijin but is there a different recommendation for 285/60/R18 D KO2's or are we still rocking the answer to life the universe and everything?
