Question for anyone with knowledge about liquid filled tires. (well a couple of questions really). A while back I acquired a 149 from a deceased farmers estate. No, he didn't farm with it, just wife's garden and yard work. Anyway the rear tires are ag's and are filled with liquid. I assume the liquid is anti-freeze since it doesn't harden in the winter. Am I correct on that assumption? Next question is what do you use to get it in the tires. Another question would be, are liquid filled a better idea than wheel weights?? Reason I ask is these current ag's are on their last lugs and when I get new ones, is filling them with liquid something I want to consider. For my use I don't really need the weight that much but I'm more curious about it than anything else. Thanks in advance to anyone who can enlighten me.
