Rear inner tube

Well-known Member
I bought an inner tube for a 11.2-38/ 12.4-38 tire and now find the tire I got it for is a 14.9-38, will that inner tube work in a that larger tire? I guess I need to write down sizes before I go off and buy stuff.
 
Just to get it right, the tire I want to use is a 13.6-38, but the tube package says "don't use in oversize tires."
Thanks kcm for your reply.
 
Tire experts will tell you they should match. But just a little expansion should be OK. Now going the other way is not good for the tube. You get all of those wrinkles and they can chafe. So as everyone said...go for it. I always sprinkle a tiny bit of baby powder in the tire, and then blow the excess out with an air hose so everything is a tiny bit slipery and the tube settles right in nice and easy.
 
May or may NOT work. Question is if it is a rubber tube it should work as rubber will stretch. Withthat disclaimer I am thinking it might just be a plastic type of material that does NOT stretch and if that then it would rip before it completely filled the tire chamber. And a lot of the new Chinese type tubes as I understand are the plastic that will not stretch.

I haven't heard of this before....but that's nothing new.

Seems to me that any material "should" be able to stretch more than its given range. That said, there is also synthetic rubber, and maybe that's what Leroy is mentioning. Don't know if synthetic is being used for tractor tubes or not.
 
We run 14.9 38's in 18.4-38's with no problems. Just make sure you use Firestone or your wasting your money.
 
Just know what I have read here on this very site from other posters and they are saying about a plastic type of tube that will not hold a patch. Just go back an into possiblys the archives and you will find a lot of posts about that.
 
Most rubber we use is synthetic. The old
live rubber tubes made from a rubber tree
were reddish orange. Haven't been made
for a long time. I have one in my shop I
took out of an old tire last winter,
would be good but the valve stem came
unglued.
 
Well if the package says 'Don't use in oversize tires' and you use it in a larger tire then I'd say you might be in for an unpleasant surprise.The folks that made the tube
might be privy to some information others may not be aware of.

I doubt that, all they did was make it to certain specifications with instructions for proper use.

Everyone knows that doesn't mean as thing as anything can be used in any manner individuals see fit and when it fails there would be a quality complaint with a rant about foreign manufacturing.
