18" tube on 19" rim

It'll work. Right?

I wouldn't

Meh, they're stretchy, why not? Let us know how it works out!

In a pinch (no pun intended) it should get someone out of the bush. I wouldn't want to rely on it long term though

It'll work fine.  Tubes stretch pretty easy.  I've seen a 21" tube in a 19" wheel.  Worked fine.

It will work but not the best ideal situation... When riding many of us will carry a 21 inch tube so that we can place in the front or back supporting 21, 18 and 19 inch diameters in an emergency case so you don't have to carry 2 tubes. But I wouldn't place an 18 in a 19 if you plan on leaving it in there for any length of time such as the full tire wear. Rubber is playable and will stretch but you are starting it off stretched and you can become more prone to pinch flats from it sinc eit would be in a thinned stretched state.

Sure.

You can troll with a 200hp engine too.

Both have about the same end result.

A 21 in a 19 is different because you're not stretching the tube though

 

Either way, I figure you're not stretching the 18" all that much. There's a ton of rubber in that tube. It's like 3mm thick. I'm sure it'll pop right on. Hell, I've seen two guys almost get a 18" tire on a 19" rim lmao!!! Drunken night...

 

 

I just ditched my 18" tube setup and went tubliss. My buddy with a 19" has a flat... I'll never use this 18" tube again. He may as well try using it eh?

 

I'll let it guys know!! I'm 90% sure it'll work haha

 

Ya I carry a 21" tube in my pack cus it will work in both my front/rear.

Otherwise I would LOVE to see a video of dudes putting an 18" tire on a 19" rim :)

I use a thicker than 3MM rear tube but in a pinch, I'm sure a 18" tube would work fine if you got it mounted without puncturing in the process.
