Calcium chloride is like sodium chloride (table salt) and will rust your rims eventually. I bought a tractor with it in the rims and had to replace both because the tubes were bulging through the rims. I loaded my tires with used antifreeze from automobiles by chucking a used powersteering pump into a drill ( screw a bolt in the shaft) then clamping a hose to the valve stem. I made sure I burped the tire when needed. I also helped load a tire by using an old auto AC compressor. You should find a garage that will give you their old antifreeze. Yes, I know it will kill animals that drink it, especially cats. I do not like the idea of using plain water because it will eventually rust the rims too. If you do not mind spending the money, it sounds like the rim guard is the best choice. Just my opinion.
Same thing i used - used antifreeze. I am now also considering filling my fronts however it does not look like I need to at this point. Unless we get a huge amount of snow later this year and then I find i need more traction in 4wd
