They are not solid rubber, they are about an inch thick. Very little shock absorption is achieved with front tires with air on a zero turn. That is where a suspension seat really helps. In my opinion, flat free, run flat tires, whatever you want to call them, are they way to go, especially if mowing commercially.
I mow a yard for a friend with his bad boy MZ. Has the no flat front wheels, to me, the front end is more bouncier as opposed to other Z turns with pneumatic wheels.
Run-flat tires do have some give, but they are generally stiffer than conventional tires, you know the reinforced sidewalls. This stiffness can result in a harsher ride, especially on rough roads, as the sidewalls don't flex as much to absorb impacts
Do you guys get a lot of flats? Are you mowing commercially or your own land? I've been mowing 45+ years, often on multiple acre lots, and I've never had a flat on a garden tractor or my zero-turn. If it isn't your own properly I guess I can see how you might be more prone to flats.

Not all of us are thorn free for example. Here I repair several tires every year from Locust and Bradford Pear tree thorn punctures. One this year actually had a three inch thorn still in the tire. And there are other things that can puncture tires including common household staples and nails of all types.
