Tire Valve info please

Dallas and Jack have good Ideas!  Use a squirt gun with the bubble soap, more fun that way. Also do not forget to check the rims, they can become pitted with rust or cracked!!!!!!   YMMV Jim

When I put new tires on my front steel wheels  the dealer installed two piece stems like on rear tractor tires, the outside part screws  out and leaves just the base. These stems are designed so you don't have to demount the tire if the valve core sticks in place or the outside of the stem is damaged, just screw out the outside half and replace.

These things are great. Unfortunately, I forgot to get them installed on all the rears when I replaced those tires.

The point for your situation is that I can easily reach these stems for airing no matter where they are located (as long as  there is a wheel hole there). I'm guessing that the reason for this is that they are slightly longer than the short ones usually found. They are all straight, not bent at all. I find that the bent ones always bend in the wrong direction anyway and I don't have the guts to try to bend them again!

NCbob..good questions.  Wish I knew the answers.  Someone once on this board discussed the different valves, cores and stems available on the market.  If memory serves (?) there are several types of cores and stems....

Depending upon the thickness of the wheel, the tire pressure range of the application (several different types available here?) and the atmosphere employeed/contained inside the tire.  Cars have one type, trucks...

And busses have another, heavy equipment another and aircraft weird stuff all alone for their tires.  Where could we go to get the proper valve stems with the proper pressure cores?  Dunno.  Yeah, snow and ice...

Could mess up long unsupported valve stems. Having low pressure cores designed for cars could cause problems with higher pressure bus tires.  And...aluminimummum wheels are thicker than steel.  Good luck.

Now to throw a little more confusion into the mix a recall!!!!
