Ballast can antifreeze be used as ballast with or without tube?

[whis]

used the same rims that came on it, no more flats plug and go. rims are the same don't matter if it has tube or not. you won't believe it but you can mount tube type tubeless if you want to, no problem's if you fill with water may leak around rim if air only. done 5 tractors this way.

Its not the water in the tire that causes the rust but the oxygen in the air. Regular air is about 20% oxygen and once it is used up the rust in the tire will stop...It doesn't take much rust to use up the oxygen....
I've been running WWF for about 12 years in my JD and the rims looked fine the last time I repaired a flat...

I have been running windshield washer fluid in my tubeless tires for 14 years. Rims are fine.
Windshield washer fluid or antifreeze work fine in a tubeless tire.
