Latex tube, what's the correct size?

[dj97223]

If you inflate it out of the tire you risk stretching only portions of the tube -- it can look a little bit like a balloon animal, if you know what I mean.

Here's my method: 1) put talc powder in a bag; 2) insert tube and shake to get entire tube covered with talc: 3) insert valve stem into rim; 4) put a few inches of the tube in on either side of the valve; 5) go to the side opposite the valve and put a few inches of tube in there; 6) alternate between valve side and other side -- this will distribute the tube rather evenly; 7) once fully within the tire and tire installed, inflate enough to see the tire start to take shape; check under both tire beads to make sure there is no tube trapped under the bead; 9) inflate more, check to make sure nothing is pinched; 10) inflate to desired pressure and enjoy.

Hi,

Another aspect of using latex inner tubes that you have to keep in mind is that you also have to make sure not to stretch the tyre bead when mounting it.

Doing so may lead to inexplicable sudden explosions of the inner tube because it has found a pathway to leave its container...

And yes, 18-20 inner tubes only belong in a tyre of the corresponding size, i.e. from 18 to 20mm wide.

Not sure if this has been mentioned but when you do patch a latex inner tube, just degrease the punctured area with rubbing alcohol and use round latex patches you cut out from an old inner tube. No butyl and no squared edges please.

Ciao,

This is the trick...same technique you should use for mounting ANY type of tube.

Not to threadjack, related matter here: I have a GP Force/Attack combo and the Force is 24mm. Can I use 22-23 Michelin latex in them? Even butyl are not made specifically for 24mm, it's an odd size indeed.
