folding innertube to fit?

Hello,

I have an old schwinn speedster, which I bought a new tire for, which was the wrong size, because the old one had a blow-out on the sidewall. got home, and the tire was the wrong size, They're both 24" but the old one is one of those wierd schwinn sizes. I thought the "schwinn sizing" only applied to 27 inch tires, but I was wrong. anyhoo, I cut up a another tire I was going to toss, to patch the sidwall, put it back on (this is months later now) and couldn't find the old tube, which hadn't ever blown but I took out before it popped. Perhaps my wife tossed it, who knows.

So the point is, I folded a 26" in there and pumped it up. Has anyone else done this? What was your success? Just curious. I don't ride this bike much, it's just a "round the block" slow cruiser...kids style with ape hangers. Fun bike, but NOT a long hauler. I know a field fix for flats is to tie knots in a tube around the hole, so why not just fold a tube that's too long? the tube width is correct (x1.5).

I know it's a hack job, and i don't usually do things this hack (at least not on purpose). so my disclaimer/excuse is that: the stores were closed and I'm getting ready to move so I want all the wheels back on my "project" bikes so they're less likely to get misplaced/damaged, and I figured a little air in the tires would help protect the rim during the move. but I tried it out briefly, and it rode fine....at least briefly, and the bulge was gone thanks to my sidewall patch.

Maybe to get home but not to run all the time.
In 700c road tire even if you got it up to pressure, something would blow pretty quick.
Tubes are cheap.

The tube will split at the fold. Replace it with the right size.

I've had good luck with doing that in a pinch, but there's a right way. I think that the trick is to shorten the inner tube by telescoping it inside of itself.

thanks guys,

I'll get a new tube AND tire someday...after the move. But if it blows before then, I'll try the telescoping trick.

Thanks again.
