Tubes for 29 2.6

I don't see tubes for 29. 2.6 tires like I have. I see 29x 2.5 and 29x3.0 does it really matter?
If not, why so many sizes so close together?

tubes will expand, i have used 29x2.0 tubes in 29x3 tires in a pinch, if you are married to tubes i would suggest the 29x2.6s off that list.

although you could just go tubeless and not worry about tubes anymore.

Lawyers[?]. A 29x2.0-2.4 will fit all of those. You have marginally more puncture protection from a 'closer' fit, since the tube is less expanded.

I used 2.0-2.4's as spares for my 3" tires, until I got a tubolito in my seat pack (which halved the space used up by the tube). My studded tire set (2.8s) has the same tubes in it, too.
 
Sorry if I disagree with the majority here, but tubes specs go by range, usually it's 2.6 to 3.0 or something like that. I would not use a tube spec'ed for a smaller tire unless if in a pinch because it would be stretched past it's 'nominal' limit. for 2.8 I would go for 3.0 if I had the choice available.

I did once accidentally use tubes for 2.0 with a 2.35 and it resulted in 3 sheared presta valves, not sue how that was even possible but once I used the correct tube it worked with no issues (mind you was my first ever social ride at JORBAFest so I could limp back home after going through my 2 spare tubes).
 
I used to use 26" tubes on my 29er back in the day I was still running tubes. Didn't notice any more punctures than usual. Just a bit harder to stretch on to the rim. Also lighter.

If the goal is to just get back to the car. I’d carry a 700cx23’ish tube.

Even a 26” tube is a pain to keep it seated on the rim while you are mounting the tire because you have to stretch it around the rim and it tends to want to slide off while you are trying to get the tire over it. I can’t imagine what kind of pain 24” would be. A skinny 700c tube is the same diameter as 29” tube, so its super easy to get it on the wheel and tire over it, even easier than a 29x2.1’ish tube.

The main issue with a skinny 700c tube is that the ride feels kind of weird - probably has to do with how much it is stretching, so it’s not ideal for keeping your ride going. For this reason I chose to carry a 26” at the time I was in the mode of doing this. I could not tell the difference in ride quality between 26”
tube and a 29” tube of the same width.

I think I just convinced myself to carry a 700cx28’ish tube with me instead of the 27.5” I’ve been carrying recently. I can’t remember the last time I had to use a tube.

I personally carry the absurdly expensive tubolito. It's so small and light. But I'll probably cry if/when I ever use it and flat it.

Those can be patched as well, obviously with the absurdly expensive tubolito patches!

I have been carrying tubolito as emergency tubes for a couple of years now, I have one for each range of tires I use (except the fat bike). Never had to use it.

I'm glad using the wrong size tube works for y'all, have at it. It did not work for me so I don't do it. If you carry something just in case of an emergency it better be serving its purpose when the emergency happens. I found out that not to be the case with a improperly size tube.

put the wheel inside the tire first, so the beads are outside on both sides.
then the tire never has to fit over the tube. this works in many tubed applications.
I also do this with tubeless fat

in this case, put the tube on, cause it is tight,
put the wheel between the beads - so each bead is outside its side of the rim
work each side on.

i don't know - @DennisG told me to do this, so i do this.

I wouldn't know, as I tend to use the correct size tube for the application. But if @DennisG told you so then it must me true, gave me a tip on fat tire pressure on the beach and was spot on. Super nice guy too. Great taste in fat bikes too.

So for me, the pain points would be:

- putting tube around rim and tube sliding off
- tube sliding off while you are trying to working parts of the tire bead on to the rim

It can esp be frustrating when u are trying to do this trail side with frozen hands. Maybe I just have always been impatient. But with a 700c tube, you don’t have to worry about any of that.

Plus, with a smaller diameter tube that has stretched over the rim, I feel it it’s easier to pinch the tube if you have to use a lever to get the tire on.
