There have been a couple of questions lately about Rim Guard. I was at my local ag tire shop this afternoon and since they are dealers I thought I would get the answer from the horse's mouth.
Rim Guard runs right around 11# per gallon and has a freeze tolerance of -35F (it gets slushy at this temp). It will Freeze solid at -50F. They told me that a lot of the big farmers in the area (potatoes, corn, soy, & lots of smaller dairies here) are switching over because of the non-corrosive nature of the product.
CaCl is 11.5# gallon and has a freeze tolerance of -40F (depending on mixture ratio). Tire shop confirmed that if you have a good new rim, tube, and maintain valve stems, you should get a long life (he said 30+ years) from a CaCl loaded tire. But if you have a leak or a flat in the field....you have to clean the rim down to bare metal, reprime and paint, and you won't be growing anything where the leak occurred for a long time.
Rim Guard is about twice as expensive as CaCl.
Hope that answers some questions folks had.
