Everything leaks. That's just a fact of life. Tubliss leaks more than
a conventional setup.

Some things, however leak too much. With Tubliss beadlocks, "too much"
is a matter of considerable discretion.

In my observation, an 18" bladder leaks around half a PSI per day,
a 21" bladder a little more, up to about 1 PSI per day. That's diffusion
through the rubber and it can't be prevented. Living with it
means checking pressure at least twice per month, which isn't too bad.

Similarly, a tire mounted with Tubliss will leak, but probably less than
the bladder. That's not diffusion, necessarily, but is probably best lived
with. You'll be checking the bladder anyway, it's little more work to 
check the tire. So long as the tire holds riding pressure for a week,
or even just a day, the best course of action is probably to leave it alone.

That's because the "reset" procedure is basically a gambling game; it may
make the leak smaller, but can quite easily make the leak bigger, at a time
when you're ill-prepared to cope. It's possible to cover a lot of ground
when checking pressure twice a day. A failed reset attempt can give you a
tire that won't inflate, or won't hold riding pressure for even an hour.
If it's rideable, add air and ride! 

My reset attempts have failed much more often than they succeed, probably
by a ratio of 10 to 1. On the successful attempts, of course I stop,
so that skews the statistics. Still, it's a highly random process and the
need to reset is far better avoided by dilligent pressure checking, especially
in the bladder. Keep it above 100 PSI as long as you have a choice.
