RV Anti-freeze weighs in at 8 lbs per gallon. Cacl and rimGaurd are close to 11 lbs per gallon. I had a set of 26/12/12 tires filled at a tire shop. It was $53 for 280 lbs of liquid. (180lbs each tire/rim on a bathroom scale) $25 minimum for each tire and did not count gallons, then 6% tax. It worked so well that I had the rears loaded on my new tractor (1026r) before it was delivered. I would not even consider iron weights in this application, the yellow ones are way more $/# than what you have listed.
