What should I get, beet juice or non corrosive? This may be the same thing and I'm confused.
First thing: Call Rimguard and tell them they're the biggest forking idiots on the planet. Ask them where their on-line list of retailers/installers is on their web site. When they give you the "no speak da engrish" routine, tell them they are forking idiots. It's the 21st Forking Century already! Who in the world has a website without a list of locations in this day and age???
Then ask if there any retailers/installers in your area. There should be, certainly in Eastern WA, not sure about Western. The closest place they had when I called a couple years ago was north of the TN/KY border, about 125 miles from me - one way. You can't buy a barrel or two, you have to physically take the tractor or tires to the installer. If it's just the tires, good luck installing +600 lb tires when you get them back.
I haven't checked to see if there are any new ones closer to me since then - why? Because those forking idiots won't put an on line list on their stupid website, you either have to call or e-mail them. Forktards.
If the question is: Fill the rear tires? The answer is: Yes.
If the question is: With What? The answer is: Rimguard - if you can get it.
The
one disadvantage (cost) of Rimguard is way outweighed by all the advantages (weight, temps, non-corrosive, non-toxic). Except of course, if you can get it. And the cost of Rimguard has nothing on metal wheel weights.

How to do it (except if you go the Forking Idiots route):
How to Ballast your Kubotaç—´ Tires | OrangeTractorTalks Note: If you use straight water (not recommended), you use a garden hose off your water hydrant. If you use a mix, like water/RV antifreeze like I did, then substitute a 5 gallon bucket (or bigger) and a small pump, like a sump pump with a garden hose outlet. Either way, you'll need that hose adapter to "burp" air out of the tire. See pic below.
