Calcium in tires, no longer a fan......

Maybe I missed it, but even if a tire is filled with the proper amount of fluid it can still leak/discharge through the valve stem when it is under inflated. By the time you notice your tires "look" underinflated, they are very underinflated. That means they are squatting which pushes the fluid up over the top of the rim and it will make a mess when you check pressure with a gauge. If you jack the rear up to take the weight off the tires, it allows the room for the fluid to settle lower than the top of the rim again. Then you can change out the valve core.
Valve cores made today are poor quality compared to the old originals. They disintegrate in a few years where the old ones lasted decades. I assume it is the brass composition in the new cores that makes the difference.

The original post was referring to a difference of 2000# using Rim Guard as opposed to Windshield Washer Fluid.

11 - 8.5 = 2.5# difference per gallon. 2000# / 2.5# = 800 gallons.

Or, put another way:
800 gallons of WWF = 6800#
800 gallons of RG = 8800#
Difference = 2000#

Oldpath05 was comparing a 24 gal. tire fill between RimGuard, and WWF, and thinking the difference was 2000#.
Of course the "difference" on a 24 gal. fill is only 60 lbs.
At issue is the 2000 lbs. difference he believes it to be.
The 2000 lbs. is a number that is totally erroneous in his posting.
The weight "difference between 800 gallons of RimGuard, and 800 gals. of WWF, is an issue for a different discussion, and has absolutely no bearing on his 24 gal. tire fill situation.

Who said anything about lids?
Non-coated steel nails should be placed vertically, and jars should be partially filled, so that nails would be immersed only partially.
The idea here, being to determine which solution will cause the most rapid rusting.

I think you have a problem with math.

If your tires take 24 gallons, that's a 60# difference. To make a 2000# difference you need 800 gallons, Which is not really a "tractor" tire...

You're the only one who picked up on that slight miscalculation, give yourself a pat on the back and a gold sticker, I always wondered why when I do my own refund taxes I seem to make out pretty good.........

We'll there's a couple points that never occurred to me, I always check psi without lifting tractor just bring valve to 12am, next time I check, I'll jack the tires up.

I like your signature, my wife has the same attitude towards me sometimes........

Not to stray too far off topic but fire sprinkler systems in buildings are plumbed with plain old black pipe and filled to capacity with plain water (no air space) and they will only "rust" a certain amount until the dissolved oxygen is used up and then corrode no further. As Luke stated above.

The topic is rust related, close enough, and no oxygen sounds true to me.......

So HE suggested lids!
I am the OP of the experiment.
I DID NOT MENTION ANYTHING ABOUT LIDS!
