I guess the tires are so old the size has worn off, not unusual. A lot of rear tractor tires have or have had fluid in them for weight. It is extremely hard on wheels because when they go flat the caustic fluid will rust/corrode the metal. Over time it will destroy them. When I get one that way I use several wraps of duct tape around the wheel to protect the tube from chaffing. Also use radial tubes, they are heaver and made out of better stuff. Just the tube is $100, so yes the tires are spendy.

When we moved here FIL told be about it. We looked into it and mine had some kind of antifreeze in it. I bought the tractor in Oklahoma that must be what was in it because I have never messed with the tires untill now.

:-laf Thanks Bill Ill just take my chances by letting the tire guys do that in Missoula when I take it down for them to do the work. I have enough medical problems rite now I dont need to add self induced poising to the works :-laf
There's an easy way to check which solution is in the tires if you are careful. Have a big glass of drinking water ready. Dribble a little of the solution out of the valve stem onto your finger. Taste of the solution on your finger, if it tastes sweet, it's antifreeze. if it tastes salty, it's probably calcium chloride. Immediately spit out the contents in you mouth and rinse your mouth out thoroughly at least twice with the water in the glass. DO NOT swallow any of the solution!! Ethylene glycol is poison and will lock down your kidneys!!

I looked on tractordata.com
They do not list the 600, but have some from a couple of years later.
This link has tire/wheel sizes:
Ford 600-800 Tractor Wheels

Most tire shops that regularly work on tractor tires are equipped with the necessary equipment to evacuate and temporarily hold the solution from the tire/tube before dismounting them and should be able to mount the new tire and tube on the tractor rim and pump the solution back into the tire.
