Michelin stuff. They're amazingly good.

I agree with Jav. We put new AirStop tubes in our Michelin Air tires when
we bought them over 1 1/2 years ago. Original owner had 6 ply tires on the
Aztec instead of 8 ply. We've had absolutely no problems so far. We check
the pressure regularly and usually only need to add a lb or two every 6-8
weeks. I find that the most common cause of those leaks is the guy that
checked the pressure before me didn't use a wrench to tighten the stem cap.
When I snug the cap up with a wrench they are still properly inflated 8
weeks or longer. If you look inside the caps, there's a rubber seal that is
supposed to seal against the rim of the valve stem, just a little pressure
with a wrench while holding the stem with pliers and a rag will seat the
seal against the stem. Just don't over do it.

I was once told by an old timer that the reason aircraft tires and tubes
leak is because they have a higher neoprene content because neoprene resists
fuel and oil better than the high rubber content tires, but neoprene doesn't
hold air as well. Anybody know the details surrounding this or if it's
true?

Thanks,
