Sooo, after riding about 450 miles, the sprocket has obviously bent the rear wheel slightly. So it is a little wonky, but not so much that you can feel it vibrate at high speed, still fairly stable.

I'm not sure if this has to do with my problem.

Had a tire go flat, appeared to be 2 holes in the inner side of the bike tube.
Tried to patch, tire blew.

Bought a new tire, examined the rim, no real sharp objects or anything near where the hole is. Examined the tread and the inside of the tire, nothing.

Put the new tire in, pumped it up to 45 psi, and let it sit overnight.
Took it out for an hour ride the previous night.
Same air pressure in the morning. Seemed fine.

Rode down the block, and noticed my rear tire was drifting with throttle?
Awe man another flat. And fast too. Got ****ed. Put it away for the night.
Came back next day to a completely flat tire resting on my rim. :|

.5 mm hole in the top of the tube again.
But not in the same place.
Still no indication of anything sharp enough to puncture the tube, pressed down roughly on the inner portion of the rim where the spokes come through in the location where it popped with a balloon (and my fingers) to see if it would pop. Nope.

Weeeird.

Maybe snakebite?

Going to try lining the inisde with ducktape, and sanding down any rough edges in the frame/sprocket end.

Im hoping this time it works, because its a hell of a job getting the break lined up, the 2 chains on, the wheel straightened and tightened appropriately, all while holding the bike up with the other hand XD
(really need a bike stand or a double kick stand)

Should I try to pump the next tube up to 60 psi next time to see if it will last?
 
If the spoke ends are touching the inner tube then they eventually cause a hole by slight movements of the tube. so the balloon test can't catch that cause.
You should be able to feel anything sharp inside your tire. Run your fingers slowly over all of the inner surface.
 
Jag is right. You gotta have the rim liner. French call it fond de jante.

If you are running 26" wheels (bet you are), I would very strongly suggest those Slime flat resistant tubes. Best flat defense ever. One less thing to fret over.

If you are running 700C (doubt it because your tire pressure is so low), you are gonna get flats.
 
Remove the rim strip and inspect each spoke head, make sure none are obviously loose.

Run a layer or 2 of pvc tape centered over spoke head holes. Then, install a new rim strip. I recommend these:

A quality tube is also a must for MaBing. We ask a heckuva lot more out of our bikes than most people. I recommend these:

A tire liner may also help, but it's not neccesary unless the roads you ride on are known to have a lot of nails, screws, and busted glass.
Oh, and goatheads!

I call it 'bullet proofing' and it's ~$25 a wheel and a MUST for the rear.
Good rim liner, HD tube, and then a tire liner.

I find Slime a total messy waste of money.
It doesn't prevent punctures, and it sure don't fix them, it just slows the air leak down.
In the mean time, you get green slime on everything when you add air.
 
Well, I would agree that the slimes are great. Ive gone over 1000 miles on a slime tube over glass and rock (as the asshats in my neighborhood constantly use the bike lane as a glass recycle bin, really really ****es me off, no respect at all) But the slime never is on the inside of the tube (rim side), so it has no effect or purpose for this type of flat.

I ended up ducktaping the hell out of the rim over the existing rim liner that was there, still could not find any indication of a rim pushing through and poking my tube, but regardless, tripled up on duck tape in the places where the flats occured, and sanded down any edges i felt were slightly rough. Then sat there and gently babied the tread until the bead was set perfect and made sure not to nic the tube.

I bought an extra thick slime tube, and rode with my little group about 10 miles without any issue @ 60 psi.

But If it does pop again, Ill go with the bullet proofing KCvale mentioned. probably put a tire liner on both sides of the tire with rim liner.
 
Going to take the air pressure today and make sure its still good.
Will update later.
 
If i can put my 2 cents worth in.
You will want to make sure the tire isn't walking backwards on the rim. When the pressure starts to wane on my motor bike the power will force the tire to rotate around the rim ever so slowly. this movement causes the tube to stretch in one area and bunch up elsewhere.
That will cause light duty to pinch puncture themselves.
It's a problem I am currently battling.

Duct tape won't stop much but better that nothing on the rim as little comes up that way ;-}

Whatever the brand, a thick tube is great.
The ones I get around the corner are ~4x as thick as the ones that come on bicycles.

I do use the Smile tire liners, but again it's just a brand, it's the material that matters.
Flexible but like frigg'n Kevlar.
It's not, but darn good at stopping intruding sharp things ;-}
 
If only my tires were a little less wide, i could get solid tires. Alas, none available for 26 x 2.125
