It doesn't. You don't "fill" the tire with fluid, you _mostly_ fill it,
then top it off with air.

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.

Yep.

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)
