preventing fast deflation

Hi All... mending a little day by day since I had my May 23rd
accident. I still have not decided if I am getting back on the A19.
If I do I am wondering what is the best thing to do to prevent a
rapid deflation of a tube tire. I know about the rim locks but has
anyone have any other good ideas. Since I do not remember anything
about the accident I have no way of knowing if I had prior warning of
what actually happened when I ran over that 4 inch nail.
The man who is getting my A19 back in order was recommending rubber
inner tubes but you have to keep putting air in them frequently.
I still have some time to think about my riding situation since I was
told I have to wait and see if my shoulder bone is going to heal.
July 21st is when I have to go back to the docs. I just learned this
morning about a friend and co worker at the prison where I work died
from his injuries this morning from a motorcycle accident. Someone
pulled out in front of him and he had no time to react.

Bridgestone UHD tubes AND Slime has been the setup I run after rapid
deflation of my front tire and separation from the rim sent me under
a guard rail and into a ravine in 2001.

Mark,
For the sake of discussion-
Why is this a good solution?
revmaaatin. who also subscribes to the (painfully) HD tube theory
note: the last time I mentioned not having flats while using those (painfully) HD tubes, my rear K270 with UHD tube found a very-angry 16p nail and kept it; shredded the UHD in a matter sec's.
So, I won't mention that I have only had one flat in 5y9m and 40K KLR miles using the HD tubes.

I have been getting very tired of having to "air" up my tires even though I put on new grippers and use some slime. (Perhaps I need to put in more) It seems that when I use CO2 the tire goes down faster. If that is true, there ought to be some other kind of gas that goes down slower. Are there any possibilities here?

Did some research. Here is the gas that will not leak through rubber:
Hexafluorid
I had thought of an invention but it seems someone has beat me to it.
Here is the link:

I just wish I had a working model.
(Hope I did not double post. The first time I posted it came back to me
but did not show up on the web site.)

Nitrogen.
Its molecules are larger than air so they don't 'seep' through the tire as
easily. Also, there's no oxygen or humidity in it to corrode wheels (if
that's a problem).
I suspect that if it's leaking fast enough to bother you, there's a leak and
nitrogen would probably leak out just as fast.

Hello Rev, From what I have read about Nitrogen, it does little to help.
In fact, because of the cost some consider it a scam. Hexafluoride is
MUCH heavier and likely would not leak through the rubber. By the way,
I took soap and water and could not find a leak. RW RE:

Since the air is 75%+ nitrogen already, I can hardly see much difference in using it over regular air, other than having it be "dry" to eliminate corrosion of the inside of your wheel.
If that were the case, if you had a slow leakin' tire and the pores were big enough for the oxygen to escape but not the (slightly) larger nitrogen molecules then eventually you'd end up with almost pure nitrogen after just a couple of top-offs (right?)
As in:
First fill: 75% nitrogen
25% volume "escapes"
Top off: 75% of 25% remaining volume = ~18% of total
18% + 75% = 93% nitrogen after just one top-off.
or am I missing something?

Try removing and cleaning the valve core ?
Thing I found using small (slow 12v) compressors is that they put air in so slow that dirt/dust has a chance to muck up the seat on the valve, try giving it a bit too much air and blast some out to clear the valve seat. Might just be dirt in them. ( Keep the covered tightly )
