Decided to go cheap for my 5.00 x 5's, just because, you know, experimental! Six months, no air added. Takes a little effort to get an air chuck on them, but pretty happy thus far.

I use those.

Jeez, Mike! And to think they came after me with pitch forks and torches for posting that I wanted to use a non-TSO’d ELT battery!😱😝

I've been waiting over a month now for the three new tubes I ordered from Van's, wound up patching the tube (NLG) so I could fly...I'll order these too, thanks for the info!

Anyone want to rig up a torture test between this Ama.com, a natural rubber cheapie, a normal TSO tube and the 2 butyl $$ aviation tubes?

I assume the key is strength at the valve stem for torture. With proper inflation and no proud mold edges on the inner tire or FOD, the abrasion resistance of long term wear would be a chore to test.

Powder, up.

Rich,

The problem with a qualification test as you suggest is that you need assurance the manufacturing controls produce a consistent product so your results are applicable to other tubes. They might be consistent properties but you can’t be sure without a significant sample size or some understanding of the manufacturer’s controls.

Well my last TSO'd butyls had pores in them that leaked flat twice before I found the rascals.

Have a feeling they CAN all work and can ALL fail, not from wear and tear or shock loads or FOD only.

Wasn't that what happened and why the astronauts were worried?

Well that about sums up the entire Apollo program doesn't it? If only there was someone on these boards from NASA to comment....

I’m one of the first guys to go cheap when I can, but it’s about risk assessment. I have used Harbor Freight copper gaskets since an oil weep is not a big deal if it fails, but blowing a tire tube on landing could be very expensive. My tires are lasting about 500 hours, so the expense does not seem oppressive to me to buy aircraft grade tires and tubes. But that’s why they call it experimental. To each their own.
