This question is about loaded tires on a tractor. This appeared to be the best group for this question to be posted on.
Traditionally, calcium chloride mixed with water has been the standard for loaded tires. It is less than ideal, because eventually something leaks and the calcium chloride solution eats rims fast. It also kills plants where it leaks.
Sugar beet juice has been used for a while, and the AG tire dealers seem to carry it, or at least a variant of it. While it is much pricier than calcium chloride, it is not corrosive, and leaks tend to not rapidly destroy rims.
Some locals have mentioned other solutions, which involve a different antifreeze agent, mixed with water. However, it seems that the local AG tire shops don't offer anything else. I suspect the popularity and availability are regional.
My particular application is with 13.6-16 on 12" rim rear turf tires, on a Ford 1510 tractor.
Does anyone have a list of current products, or better yet, recommendations for filling loaded tires?
