Other than the freeze protection alcohol which is the non drinkable type, What is toxic about WWF??? I have used it in every tire I have loaded. OK call me a tightwad, and suffered a little sticker shock when looking at other options
How much weight you get does depend on the fluid you use, but also how much you put in. Ag standard is 75% of capacity, mine are loaded 98+% thats 55 # in a 23x10.50 -12. With the air out of the tube I pumped the WWF in and hydraulically seated the tires, then removed 1/2 gallon. That put it at 5 PSI so added a little air to get 12 PSI. Been running like that for 10+ years
Near as I can tell, "-50 RV Antifreeze" is around 55% propylene glycol. I can get it for 2.70 per gallon delivered. I'm going to dilute it 44% with water, which will move its freeze point to around 0 deg F, which is more than safe around here. That makes it within 5¢ per gallon of the cost of WWF. From everything I read, it does seem like either one is fine to use. But this will be a few ounces heavier, so that's the direction I'm heading.
Like Gordy I'm shooting for as near full as I can get, hopefully 95 lbs per tire

Don't dilute to much as you lose corrosion perfection qualities as well . I break the bead on the valve side , push it open and pore in as much as I can get then put a few pounds of air in it to get the bead to seat. Usually easy because it is wet and full .

Ya type of alcohol and lack of corrosion protection , plus the weight adds up if you really need it .

Also if max weight matters to you, don't dilute the RVA. It is heavier than water. The WWF is lighter than water, but I have plenty of cast iron WW's so it is not a big deal to me.
While on the subject of weights, it's worth searching for a combine wrecking place around you. Some of the JD combines used wheel weights which fit perfectly the 16" wheels of the 4xx series tractors. There are two types that fit:
Model H78062 = 104 lbs per wheel
Model H93849 = 162 lbs per wheel
I was amazingly lucky to find a set of each, but I had to go some distance to get them.
Initially I was going to fill the tires too, even got the fluid! (also tens of dollars because we don't dilute our fluid here in ). But then after I got the combine weights I lost motivation to fill the tires.

For those that don't know these are for the inside of the rim and made of 2 halves that bolt together to fit around the spindle.
I was snooping an online auction and noticed them but didn't think much because the description sucked just "Wheel weights" Luckily there was something else I needed to check out on inspection day. When I saw them in real life the light went on, ran back to the truck and grabbed pen, paper and tape measure. Made notes and took off for home to measure the 448's rear rims. At the end of the auction, with tax and buyers premium I owed $20 and change for the weights
So... I ordered RV Antifreeze from Walmart.com. They would only let me order 12 of them. Shipping was free after $35, so I added some paper plates and checked out.
Earlier today I received 7 of them on my front porch. Cool. But their email said they sent me 8 of them and still owed me 4 of them. SO I clicked on "return", qty. "1" under reason "wrong quantity received". The form said they'd send me a replacement.
So just now I got a call from a DoorDash driver. I never order DoorDash. (Restaurant food delivery) He says, "Where do you want all this stuff?"
"All what stuff?"
"Some kind of... RV Fluid or something."
"Oh. Just leave it by the garage. Thanks."
So I wait a few minutes, then head out to the driveway. Did they send me the qty 4 that they originally said, or have they remembered to send me all 5 of what they owe me?
Well..... What if I told you that there are now:
TWENTY ONE one gallon bottles of RV Antifreeze in my driveway. Are you serious??? Added to the 7 they sent earlier, I now have 28 gallons!
I don't even know how to handle this. Load up all but the 12 that I ordered and drive them to my nearest Walmart and try to convince them to take them back?
There's no return option on their webpage for, "You sent me WAAAAAY too many of them!"
Ugh.
"Never be afraid to try something new. How hard can it be?"
12 21 they both have a one and a two in them what's the big deal, easy screw up must have been the paper plates that threw them off, but don't worry 6000 will show up tomorrow
