The tire rims are in good shape where the tire beads sit, no rust and only very minor pitting which I sand out when mounting a new tire. With five Cub Cadets to maintain I replace two or three front tires every year. I do have plenty of briars on the edge of my lawn which are tough to avoid while mowing, so I think thorns are causing the punctures.
I looked for, but didn't find, any 16x6.50-8 thorn resistant inner tubes, if there is such a thing. I've seen a few YouTube videos on filling the tires with Great Stuff expandable foam, but that foam becomes brittle and doesn't flex, so I have not tried it. Is there an expandable foam that stays relatively soft after curing and won't crumble. Or any suggestions?

What about a tire liner/tire guard. Its a thin liner that goes between the tire and the tube, is impervious to puncture.
Something like this. Or something similar from a different supplier.

Different application but the concept is the same, I use this kind of stuff on racing bicycle tires for glass punctures (a product called Mr Tuffy). Works awesome where before, even a small glass shard would cause a high speed flat and loss of skin, the tire liner 100% solved that problem.
