AntiFreeze, I have been told that calcium causes problems down the road. I have no clue as to the wwf's long term issues so AF seemed like the logical choice.

If there are any chips or nicks on your rims then you will have a corrosion problem with adding water, I don't know if wwf has any anti corrosive properties, but I do know that AntiFreeze does. It's just like a compressor, it will rot from the inside out and you won't know till you go to change a tire or it fails......
I am sure one of your local tire shops fills tractor tires, I think the going rate up here was about a buck a gallon. I got them to do it for .60 a gallon and I thought that was still high plus the cost of the AF. Took 44 gallons each in the rear and 4 each up front, cost me 60 bucks for the fill plus 2 cases of AF. But the handling was night and day, it might be a little nimbler without but I have alot of rolling pasture with gully's and some steep slopes. Keep the seat side up /forums/images/graemlins/grin.gif
