I'm pretty sure that foam filled tires on a Cub would beat the operator to death.

I used to occasionally run a rubber tire Hi-lift, that had foam filled tires, it was the same way.

Not sure if it's the geometry, the weight distribution or just the nature of the beast of a skid loader but you don't notice as great a difference in foam filled vs air filled tires as you do with other equipment. There is a difference, and you can tell it right away, it just doesn't seem as bad. (this is based only on my own experience... your mileage may vary)
