43x16.00x20 tubes available anywhere?

[mr.offroad]

Looking for these tubes for my John Deere 3120. Calcium's leaking through the wheels, and I'm done with it.
If not, is there an acceptable substitute?

Use a 10.00 or 13.00 x 20 tube. It'll stretch easy enough.

If your rims are in that poor of shape tubes will not help much.

I never picked up on that but you are right. I honestly don't know why people even bother with calcium.

To the OP. You might as well look for different rims.

It was and still is a less expensive way to add ballast that will not freeze.
Also those rims would be getting close to 25 years old, so not a terrible life span with calcium.

I also do not like calcium but I understand the price difference especially 20-25 years ago.
The price to calcium water fill a tire was very minimal, do it yourself for under $30 a tire service truck would be $40-50 back then.
I much prefer iron for weight myself.

I also have a 4410. I have no fluid in my tires and I've never felt the need to have fluid. I have 600 lbs of cast iron that I use less than 5 times a year.

Edited to add that there is a chance that you can find just the rims on the internet and have your original centers welded into them. I've done this on several rims for customers. I'm not sure it would be cheaper but it is another option.

I used to work in a tire shop when I was young. Worked on lots of tractor tires with calcium chloride. I hated the stuff. The beds of our service trucks were all rusty, and the tractor wheels as well. We had a running account with a local welding shop. Then they started putting it in tubeless tires without installing tubes. Just stupid.

Not necessarily stupid, years ago there wasn't much to choose from calcium or iron. Back then it was even more of a price difference between iron and calcium, then it is today between beet juice/rimguard and iron.
As far as going calcium in tubeless tires they didn't rust completely through much faster then tubes tires did especially if filled so the rim was never out of the solution.
As far as rust on a service truck, yep if not well rinsed after working on a calcium filled tire it sure would. Just like the rims would rust out much faster if the tire monkey wouldn't wash the rim and tire well before reinstalling it and refilling it. Some of that was a result of the farmer standing there waiting for the tire repair to be done so he could get back to work with that tractor. Some because the tire man was hurrying because of the next job waiting on him. And some was because it was a royal pain to get everything washed down good enough.

As I have said I much prefer bolt on iron to any kind of liquid fill, how ever I am well aware of the cost difference in liquid fill versus bolt on iron.
