True or false ?

Postby RandG » Thu Nov 22, 2012 12:40 pm

An inner tube can be damaged by lightly inflating it outside of the tyre .

You should lightly inflate it before putting it in the tyre

This

What is your definition of "lightly" though?

For me, lightly is just so it takes shape.

Let me rephrase then, inflating the tube outside the tyre damages the tube, true or false ?

As above, you are supposed to slightly inflate it outside the tube so make it easier to fit.

Inflate it too much and they will eventually pop, as it thins the rubber. But they inflate way more than you'd think, like rubber rings you see in swimming pools!

if you are in a pin factory then true.

otherwise false.

I know this comes over as looking obviously stupid, but I want to get opinions on this before I add to the story.

I recently received some tubes, on unpacking I thought I'd inflate a couple just to check the width compared to the ones I already had.

First one I inflated went very deformed, narrow in bits, mega fat in others, very strange shape :? Then I inflated another, very similar :? Then I inflated another couple, they were fine, so thought, inflate them all to see how they are, overall, of the ten I bought, four were very deformed :shock:


I emailed the company today about them, and in fairness to them they said they would replace the four deformed ones, however, it was him stating I have damaged them by inflating them outside the tyre :?

Can't say I have ever heard that before :?

Of course you can damage them by inflating them outside of the tyre. Just don't pump them up much!!

Seems way too complicated for me. This is how I do it;

1 - buy tubes

2 - put two tubes in Camelbak

3 - if I have a puncture I remove the tube and put in one of the tubes from Camelbak

Missed out step 4;

4 - when no tubes left, consider going tubeless...repeat from step 1 :lol:

Why on earth would you inflate a tube outside the tyre to check width?

And yes, they'll be slightly deformed, the rubber will be slightly thicker in places. It wouldn't be a problem in the tyre as the tyre helps the tube to keep a uniform shape. But when you start inflating a 2.35" tube to 4-5" with nothing to retain the shape.......

I have to ask, because it's going to bug me otherwise.

What exactly did you *think* was going to happen?

hehehe.

I think I've got some old DH tubes in the garage somewhere. I can see a video of me "testing the width" by sticking one on a track pump going on youtube later on.

big boom!
