!5" tire tubes?

[jugbutt]

I got a set of very used 31X10.50-15 mud tires and I was going to put tubes in them Just to be able To get the street tires off the jeep so I could hit a few firelanes and gravel roads around here I'm going nuts and things are tight.
Anew friend Gave me the tires so I could riding til I could get some new Rubbers .
What size tubes will I need plus where could I find some ? I will be using the factory wheels.
Thanks for your help!!!!!!!!!!!!

You could probably go to a truck tire repair shop in order to get tubes. Tubes, I have heard, are very expensive, so it may not even be worth the money to do it.

Why do you need tubes? Do the tires not hold air? Are they punctured?

[jugbutt]

I think he said he aired them up and they didn't hold air and one has a plug.
Truth be told they might be leaking at the rim what you think?

Pop the beads, clean the rims, and reseat the beads. If they're still leaking then I'd just scrap the tires.

The only problem with tubes in a radil tire is the steel cords will poke the tube if there is a punture or cutsidewall

Yea I think your both are right.
