Are the lighter alcohols (ethanol, methanol, isopropanol) hard on rubber? I'm not sure I'd put them in a tire, although I'm not seeing a lot of notes about it.
Personally, I don't think I'd put anything, except perhaps beet juice in a wheel without a tube. Perhaps use a tube for everything. Check what you have.
I'm having troubles finding the actual cost of beet juice.
Here it suggests that
Beet Juice is $3.20 to $3.60 per gallon, if sourced locally, and filled private containers. I can buy used plastic 55 gallon barrels for about $10 each. Thus, it could be competitive in cost with other liquid antifreeze options if one can find it, and fill one's own tire with it.
I'm seeing beet juice for deicing could potentially be less than $1 per gallon. Is it the same stuff?
I just bought a pair of rims to adapt to my Toro that had Calcium filled wheels (one with a tube, one without, both had quite a bit of rim corrosion, but the one without a tube now has eaten a hole 100% through the rim.
My Ford has some light corrosion where the valves have leaked Calcium, but not too bad. I think I need to replace one tire valve now.
I'm just buying an older Massey that has had massive wheel damage on one side due to a leaking valve stem and calcium. It'll need a new rim, and tire.
