(I didn't read the mass of single-Spaced run-on text)

HD Tubes, they're roughly $15 at bike shops*
.. AKA Thorn Resistant tubes .
* Don't Have One? No shops around? the Below will sell online/Mail Order
[Seems like you commit to buying it (add to Cart) then, they price It]

I use them in my Bike Trailer wheels ..

Its still the tire casing doing much of the work ..
but if they're thrashing tires I wouldn't blow $60 each .

Inner Tube has no structure all strength of its own.. any more than a Balloon does.
