CaCl doesn't do a tractor any good under the same circumstances although it can be flushed off easier. A problem is that you can never seem to get at every nook and cranny.
Rusting rims - Goodyear (their old handbook since Titan owns the US ag business now) and Firestone recommend filling tubeless without tubes. Their books say that even if the rims are not completely covered with CaCl solution. There is only so much free oxygen to cause oxidation. Once the oxygen is gone, rusting stops. Better yet if inflated with pure nitrogen. The oxygen in H2O is not free to cause oxidation even though one thinks of salt water as a horrible rust agent.
The worst rusted rims I have seen are tube type tires filled with CaCl solution. Solution leaks out of the tube to valve stem interface because of tire movement shifting the tube - remember the stem is anchored in the hole in the rim. Creates a small leak, salt water gets between the tube and rim, the tube type tire is not sealed so air can get in. Air, salt water, rusted rims. Picture attached is the rim from an older tractor, tube type tire with tube, customer brought it in because it was leaking at the stem. He went away with a used rim from an old tractor that had never had ballast.
