I just walked about two miles home after getting the second flat tire in a week. Not a puncture, a flat caused by an internal failure of the tube. Yes, I know I need a jack. On the list.

The facts:

- All tires, tubes, flaps are brand-new.
- All have occurred on the same wheel.
- Nothing external punctured the tire.
- The tube seems to be pinching on the interior of the tire (according to the tech at GCR), which I've never heard of before.
- I'm running 30 front, 35 rear (this wheel is the passenger side front).
- The truck was aligned a couple months ago, drives straight & true.

Questions:

- Has anyone else had such a problem with a tube pinching & puncturing on the inside of the tire?
- Would applying baby/talcum powder to the tube prevent this?
- Where can I have these (multiple expletive deleted) wheels rebuilt for tubeless tires?
- If a tire isn't marked "Tube Type", can one assume they can be run tubeless? If the answer to this question is "no", then I have to disregard any answers to the previous question: another set of new tires isn't in the budget.

Off to retrieve The Curse and and buy a jack at HF...

Thanks for any help provided, and happy holidays.
