Is there such a thing for a 33.12.50 and were can I find one?

 

Check your local tire store like discount, or big o, or america's tire, etc. I would think they should have some or would know where to order some. Look at it this way, if they make ones big enough that you can sit in them and float down a river, im sure they make one for a 33x12.5 r15.

 

They make em for semi-tires. Not sure it they make em for that size though.

Why do you want an inner tube?
Got a hole or a slow leak?

 

Im gonna go out on a limb here but i would guess he probably has some sidewall damage and cant plug it but wants to keep the tire.

 

Yeah its right around the rim.My buddy tried to put the tire on the rim with screw drivers and such, Tore the lip up quite a bit.Still don't under stand why it took this long to cause an issue.

 

How much thread is on it? You can pick up a used tire pretty cheap to finish off your set.
