Is there a risk of rim corrosion using antifreeze and water?

No. Unfortunately tubeless wheel setups eventually rim seep. Antifreeze is tasty to pets and wildlife and poisonous. Beet juice is the number one preferred filler as noted. Calcium Chloride is very common but as also noted is corrosive. Inexpensive water and windshield washer is a low cost alternative good to about -20'F. Polyurethane foam is costly, but gives max weight at about 12lbs/gallon and won't freeze. I have 2 sets of tires. The older ones, 30+ years have calcium chloride and one of them is rim seeping. The other pair have tubes, also calcium chloride filled. No signs of seeps and I've never add to add air to keep the pressure up.

I ask everyone I can about things like this, and more than a few have cited corrosion, but I don't know what solution is the bigger culprit with that. I've also heard about two piece rims, and I assumed that meant an inner, lug nut section, and outer tire mount area, but I could have misunderstood that too. Beet juice was the most recommended fill. We have a Class VII telehandler at work, and those tires are foam filled. There are bolts and screws into the tires and no issue, but I'm thinking that is done so you never touch the tires again. That thing is a beast.

Kinda. A split rim is a wheel with a full rim on the back side of the wheel and a smaller diameter grooved rim on the front of the wheel that a rim lock ring locks into when the tire is pressurized.

So is that like the bead lock rims that they use on rock crawler vehicles? Those have a lot of bolts all around the rim though.
My understanding is that they use those because they run such low pressure in those tires, and they can drive the tire off the rim.
I'm guessing that a rim like the one pictured has to use a tube, or the air will find those gaps and leak out.

Interesting tangent, a buddy up where I live now is big into demolition derbies. They're usually associated with our county fairs, but some are stand alone if you're into that kinda thing. Saw him out in out in WalMart one day and he said he was there to get a tire tube. My mind went right to a bicycle, and he laughed and said no, for the derby car. Makes total sense that you'd want a tube in your tire in that situation to keep the tire inflated and your vehicle moving longer. Another thing I never thought about but seems completely obvious once you hear it.

I don't know what rock crawlers use. Split rims do require a tube. 50+ years ago split rims were common on pickups, log trucks, semi's, construction vehicles, etc. Today, I believe they are illegal for highway use. I think they are still common on off road construction equipment.

I have seen split rims when I was a kid that only required a boot and not a full tube.

I checked my Branson and kit has Ag2’s. I never knew what the Ag was before.
