26 Tubes In 24 Tyres

Recommended Posts

After I rode on picreleated without any issues I thinked about putting 26 tubes(1.95") in my 24 (2.4") tyres because I run out of 24 tubes and don't want to buy patch kit.

And I also has a bunch of punctured 26 tubes. What if cut them to pieces and use like a patches?

Well) It's Russia, so patch kit costs £4-5 and tubes for £2-3 is CRAP (some non-elastic chineese (wancheng or something) bad quality crap). Maybe it sounds strange, but it is a problem to find good quality tubes here.

Yes, 26" tubes will fit in 24" wheels. I generally fold an inch of overlap at the opposite side to the valve in a vague attempt to keep things balanced. I wouldn't recommend a 1.95" tube though!

Also, it might be completely unrelated but I puncture a whole lot less when I run 24" tubes.

Because the thickness of the tube is designed to be at its optimum in a tyre that's 1.95" wide, so by stretching it to 2.5" you're just making it thinner. A tube rated to a higher width will be thicker, so it'll have less chance of punctures.

If you've had no problems then why does this topic exist? ;)

Stupid... Or stingey?

Stupid.

Yes, you can use 26" tubes in a 24" tyre, and yes you can use bits of tube to fix punctures.

Make sure you sand it a lot though. It doesn't bond as well as a patch, so you need to really rough up the surface.

Also - don't try and stick it down on the side with the chalky stuff on. That just doesn't work ;)

Edit: When putting a too-big tube in a wheel, I find stuffing it inside itself to work much better than folding.

Like this:

And put this bit opposite the valve to try and balance the heavy spot out a bit.

I've used 26" tubes in my mod quite a lot of times doing this :P
