tube came out with fold marks

[keener]

I meant to post this for a while...I change a Hydano rear tire of my 950 that lasted over 17000km (Toronto, California round trip + riding more locally).

Anyway, the tube came out like this? What does it mean? Was the tube too big?

I think the size was 140, not sure. It was a ultra heavy duty. I had no problem and did not feel anything unusual while I had that tube and tire on.
