If you fill a tire with water, how does that affect the pressure? Do
you just add air to bring it up to its rated inflation pressure?

It doesn't. You don't "fill" the tire with fluid, you _mostly_ fill it,
then top it off with air.
Does
the water affect the handling (other than the added weight)?
Not if you fill it more than 3/4 full. You can sort of feel the "slosh"
if you fill it about half-way, at least at road speeds.


I suppose you should always use a tube, to prevent rusting of the rim.
Yep.

For a tractor that's only used in the warm months, would there be any
harm in using water only, if the winter temps only go into the upper
20s at night (maybe let out the air at the top of the tire for winter
storage)? I'm wondering if the freeze expansion could be accomodated
by the extra slack in the tire.

It's not even a problem if the temps go down into the low teens, as long
as it doesn't stay below freezing long enough to freeze the water. A
rubber tire (and possibly a tube) are fair insulation, and even the
little tires on an 8N hold ten or more gallons each. (what? 26-18.5? I
don't remember, and I owned one up until about ten years ago)
