Moose,
I haven't tried using anything but what the tractor folks put in, but I
doubt that expanding foam would work. First, you need the foam to
support the weight of the implement. The tires on mine run about 30 PSI,
which is quite a bit lower than what the foam could exert, especially
the low expansion foam. Another thing, when you use that foam, and press
on it, it usually deforms and doesn't come back fully. I don't think
this will help your tires. If you want to give it a try, fill a small
innertube with it and see what happens.
Having tires filled with rubber is costly, and should only be done on
new tires so they will last as long as possible. We had a 150 acre
pasture with heavy Mesquite to shred, so we had it done to the front
tires of the tractor. They weigh a ton now, but the thorns don't send us
into town to the tire shop every day. Some of the thorns are so long
that they were able to penetrate the rear tires on our tractor, but only
a couple!
