Inner tube width size

[OurJud]

Hi, I'm wondering if anyone can help with the varying width size of inner tubes. I admit the reason for my query is a little unusual, but I assure you genuine.

I'm currently designing a minimalistic wallet and would like to use a rubber band cut from an old inner tube, as a means of securing the wallet when closed. I've tried using a standard MB tube, but it is far too small for my needs and ends up super tight when in place. No good.

The distance the band needs to span is that of a credit card, end to end (about 8.5cm), and I was wondering how inner tubes vary in size, in terms of their width when laid flat.

An ideal size would be about 7.5cm. Does anything of this size exist?

Thanks in advance.

No idea, but have you tried an oblique cut as a means of getting a longer rubber band?

Mmm, no, I haven't. I'm just trying to visualise this in my head. Would the ends not be at a strange angle to the length? Hang on a mo, I'll go and see how this works out. Thanks for the reply.

Nah, that didn't work. I'd have to cut at a very shallow angle to get the required length, but as I suspected this results in weird 45 degree ends which means the band wouldn't sit flat when in place.

Thanks for the idea anyway.

Trot along to a local m/cycle breakers and get one from a small bike/moped.

Ooh, that's a good plan. Or a wheel barrow tyre.

A 26x 2.2- 2.5 inch MTB inner tube stretches taut over the length of a credit card. Cut diagonally as suggested by Tim is slack on a credit card.

You could try a Downhill inner tube, but look for ones that go over 2.5 inch

how's about just using a rubber band?.. they come in all sorts of sizes

Or a charity wrist band.
Ob. Cycling: I believe Livestrong ones are a bit of a glut on the market.

Thanks for the help, everyone
I did, of course, consider regular elastic bands, but I suspect they would perish much quicker than inner tube (nothing to back this up, I just suspect it to be the case) and besides, I've been unable to find them at the width I want (about 12mm). Much the same for silicone wristbands. I can get the width, but the silicone is too thick.

I'll give my local bike shop another call tomorrow and see if he has any of the 2.5" downhill tubes. Failing that I'll try a m/bike shop as also suggested.

Maybe @Arch can help: she makes handbags and other wonderful stuff with old inner tubes.

Thanks, Pat, I'll drop her a PM

Or at least I would if I could figure out how

That'll be it, then. I'm pretty familiar with forums and how to send PMs... just couldn't find the option. Anyway, I went to her craft site and emailed her through that
