Allis Chalmers D15 Bad Rim Fix

Hi. I"m new here and appreciate any feedback. I inherited my grandfather"s 60"s vintage Allis Chalmers D15. The wheels are loaded (I assume saline) and I have noticed that the rims have become increasingly rusty. The other day when I went out to start the tractor up (it was a little warmer) I noticed that the valve stem had blown out of the rim and the tire was flat. I jacked up the axle to take the weight off the wheel because it looks like the tire is still fine. Money is tight, so here"s my question. Can I just get an inner tube and have that installed, or should I buy a new rim? I appreciate any and all feedback.

Things to do with one like that is pull the tire off. Clean the rim real well wash it off real good first. Then paint the rim or even better us a spry on under coat type stuff. Get a new tube and fill with fluid again or drain the other side. Having one full and one empty is a good way to flap a tractor over. Any more I use a winter grade wiper fluid to fill my tires that way it does not cause rust and is animal safe. I also do all that work my self
 
Thanks for the thoughts. Any suggestion on how much to fill the tire with? WOuld I also leave room for air at a certain pressure. Sorry to sound naive but I'm new to this stuff.. and definitely don't want to be flipping it over.
 
Cost to have some shop do it all will be more then $100 and that was back 10-15 years when my dad had one done. I do all my own tire work but I have also been doing tires since I was 16 and that is a few decades ago
 
With the valve at 12:00, you fill until the fluid is to the top of the rim, then pressurize the tire. ie, it"s about 3/4 full.
 
Not as big of a job as some would like you to think. I repaired the wheel at the link is an evening while I was subing for one of my night foreman after I found a chunk of a rim for the patch. Not all are this bad but some take larger patches. Some times for just the valve stem you can find good steel that you can patch with a large flat washer.

1. Take tire off rim.
2. Clean up everything as good as you can.
3. Weld the valve hole shut, with either a patch from a donor wheel, or some sheet steel, bent appropriately, to match the hole.
3. Drill a new hole somewhere other than the patch, and use it for your valve location.

Remember that your welds don't have to be air tight, just smooth, and spatter free, on the inside, with a nice thick coat of paint, to prevent rust, and to smooth things out. An old tube, slit down the middle, with the valve stem pruned out, and placed outside the new tube will keep the new one from chafing the new tube against the welds.
 
To all of the super people on here who replied:

Thanks so much. I appreciate the great advice, including pictures. After all of the feedback, my plan is to purchase a couple of used rims and tires, and use one rim to repair the bad one I have. That way I'll still have an operational tractor, and won't tie up too much cash in the repair.
Best regards,
John
 
Rusted out valve stem holes can be repaired easily if you have a torch. I have shaped a piece of sheet metal, at least 16 ga., to match the rim. Braze it in place, smooth out the braze and redrill the hole and you're ready to go.
 
Here is how I put window washer fluid in
