What causes a tube to do this?

[zanny1]

1952 Case VAI. Sat 15 years outside, before I bought it a month ago. New tires many years ago. When I got her the left tire was flat, but pumped up fine and held air until now..... a month later. Changed the tube yesterday. Rim looked good on the inside, but the tube was twisted. Is this a result of improper installation 15 years ago, or from sitting flat for God know how long?
Also. all the clamps on the rim were loose and had to be tightened a bunch. Rim may have moved on the wheel hub at one time.
A mystery to me.... hope the right side is not the same. Big hassle to get the tire off the rim and change the tube.

Since the rim mark on the tube looks consistent, I'd say it was twisted when it was originally put in.

Is it the right sized tube?

Improper Installation has my vote.

Is it the right sized tube?

My first thought was also, tube too large for that tire.

My guess is not enough baby powder, and/or too big of a tube. Looks like it was put in twisted and couldn't right itself because it was sticking to the tire and rim that way. steve

I believe the prior posters have it correct so I just want to point out that you shouldn't be surprised by what you come across. At least this was accidental, the deliberate screw ups that are an idea of someone's fix, are the one's that aggravate me.

Had an experienced tire guy out working on an 18.4x34 on my 4020. It wasn't too much later the tire went flat. I took it apart this time. Somehow he managed to put the tube in backwards! Such that valve was on the wrong side. I didn't know this was possible. So it lasted for a few days before the tube ripped right away from the stem!
Back when I worked in a shop, we did some tire work. Often would take new tires off of combine rims, widen the rims, and install over size tires. We had a large, short handle hammer which was handy for tire work. It came up missing. Then a few years later customer had a flat. Guess what was found in the tire?!?!
I've taken tubes out of tires with various maladies. Wrong size installed in the first place, not inflated/unfolded before installation, not lubricated properly/dirty tires/rims, etc. etc.

Tube marked 11.2/12.4-24 which is correct for the wheel.
Got to wonder if sitting flat for many years caused this, or the tube was installed poorly.
One thing is for sure...... I've never seen anything like this in my 40 years of restoring old tractors.

Tubes don't twist themselves in the tire.

You have found the reason why a good tireman will inflate the tire and let all of the air back out, then inflate to the right PSI.

I always deflate twice with tubes and use tire talc . Might not be necessary but it works. I only do my own tires so labor costs are low wise.

Saw it a couple of times. My thinking was the tube was put into the tire then the tire was put on the rim, inflated trapping air and put to work.

The tube should be put in the tire, inflated until the tire starts to raise off of the rim to expand the tube and expell the air between the tube and tire. Then deflated tire put on rim and repeat the inflate to seal the bead and deflated. Once that is done. Then inflate to proper psi or fill with fluid.
