No, it is not. That’s why I made it. The elastic properties of the rubber are reduced if you just pull it out of the box and install it without expanding it first. It’s also just common sense to do this to remove the wrinkles. I’ve been lazy and failed to expand the tube first on my kid’s BMX before installing it, to only replace that one again a couple hours later.
That was more my point, improper installation causing popped tubes, you don't have to stretch it, but you do at least need to slightly inflate it before putting it in the tire, this helps keep it aligned and eliminate pinching. I have heard many people exclaim you have to stretch the tube but it doesn't stop pinching if the tube has been improperly installed.
So far as the name calling...very childish Mike. I expected better from you.
