Latex tubes , Hold air longer and puncture resistant???

Looked at some tubes made by Air - B. The box describes them as
holding air 10 times longer than regular latex tubes. They also claim
to be puncture and pinch flat resistant. Supposed to be lightweight
too. Is this a bunch of marketing hype or??? Are latex tubes normally
more puncture resistant?

Thanks

I'm not familiar with these tubes so I don't know what is different
about them from normal latex tubes. Latex leaks air so fast that the
normally used racing tires needed daily inflation. That latex is
better in pinch flat protection should be obvious from the ability to
stretch many times more than butyl rubber before it breaks. This is
essentially what causes a pinch flat, the compression and lateral
squeezing out rubber.

On the other hand, there are a lot of bad reviews at:

Reading these makes me doubt that these people know what is happening.
They talk of blowouts, which to me means "BANG". If you heard the
bang then the tire was off the rim. So how can I believe this is tube
related. Another writer claims the base tape cuts the tube. This is
an old saw and an excuse for tire lift-offs that cause long blowout
slashes in tubes.

I don't know what to make of it but I don't care for latex tubes. My
rolling resistance and weight is just fine and I can go on a four week
bicycle ride without pumping.

Hold air 10x longer? I don't know; both of mine blew up while I was
inflating them.

Let's face it, inner tubes just aren't that exciting. Spend some time
inspecting your tires for glass and crud before each ride if you want to
reduce the number of flats.

As I said, latex tubulars required daily pumping and my 700c x 25
tires make it a month without pumping. I call that at least 10x.

I don't know; both of mine blew up while I was inflating them.

I'm interested in how that occurred. Did you hear them make a bang?

I call explosions exciting.

Spend some time inspecting your tires for glass and crud before each
ride if you want to reduce the number of flats.

I think that is too late. If the tire isn't punctured by the time you
get ready for the next ride, it won't happen. Flats occur in a short
time after the sharp object engages the tire.

I had one go `BANG" .

Left an inch long gash in a Conti Grand Prix tyre - which was close to
being new (used only 2-3 times). The tyre did not come off the rim

Is it safe to say I can blame the tube? It is not only only time one has
gone `BANG', so I do not use them any more
