So I got them installed and I was itching to find out how they would work on steep ground and, would they damage the lawn.
I got the Carlisle tires and man are they aggressive. Almost an AG tire. I headed over to another kind of steep bank with more sparse grass, moss, and weakly-rooted weeds that I cut every other week for a guy. What I found was that the tires were very rough on that area. Unless you drove very delicately, the bar tires made unacceptable marks in the sparse weakly-rooted "grass". I was kind of disappointed, but not surprised. I was very pleased with the traction, but if you put a cowboy on a zero turn with those bar tires, it'll look ripped-up in no time.
I then went home to my 3 acres of healthy lawn and cut some of it. My lawn is nearly flat. There, it went a lot better. My grass is pretty thick. It can take the "bite" of the bar treads and even some light slipping from the bar tires without leaving marks. I made some fairly tight, but not "zero-tight" turns and not much if any damage. However, anywhere where the ground was soft or patchy, making a turn leaves a pretty nasty mark.
The final analysis wont happen until I can cut the huge bank with the pond at the bottom. The grass there is not as good as my lawn. There's a lot of moving pieces to all this. I want to do a good job, but not slide sideways and end up in the pond. I also don't want to damage their lawn.
The traction is unquestionably there. Now can I keep the damage minimal.

On a slightly related topic, I have my eyes on either a used Deere 1565 or a used Kubota 3680. These machines are part time 4WD and offer much better traction. Even with turf tires, they get very good traction. However, they sit higher (higher center of gravity) so not as good under tree branches and not quite as maneuverable. I promised myself I would get 2 used machines. It will be interesting to see which one does better on the pond bank.

With practice you should be able to do it with no damage. If you’re not a good operator or are careless you can rip up a yard in a hurry. I’ve never received a complaint from torn up turf from my machine.

Nice Magnum in your profile pic.
As far as your zero turn can't help on that much, only thing would be if your air pressure can be lowered without losing stability on the side hills.
I didn't get a 3680 but I did get an old Kubota F2000 last year after trying out several zero turns and other newer mowers including a ventrac, the F2000 with that big front deck sticking out and 4wd is the best mower I have ever purchased, I would recommend any of the 4wd front deck mowers for steep areas mine feels almost as stable as the Ventrac was.

My midmount Grasshopper is a better hill mower than the F2560 Kubota. I’ve nearly tipped the Kubota on hills the Grasshopper is solid on.

Finesse is key! It's easy to shred the ground with a ZTR even with turf tires. With the bar tires I find you get way more control and less sliding but that doesn't mean you can operate the controls like toggle switches.

If I had really steep slopes to worry about I'd choose a 4WD CUT or SCUT with R4's. Even turf tires on a tractor will slide on steep slopes. In 4WD the tractor will tear up the turf in the turns too.

Hay Dude, what psi are you running in the new tires? On Grasshoppers they use only 8psi, and get better traction, smoother ride, and less damage.

Right now theyre inflated to ~20psi.
I'm in agreement with you that lower inflation may "soften" the tires, but there may be an unexpected downside.
The tires are very "rigid". I would have preferred something a little softer. maybe underinflation would help.

20 PSI makes for an unnecessarily rough ride.
I've always ran 8 PSI (front and rear) on my zero turns.

Going to try 15. Mowed some more healthy lawn today. Barely left a mark.
I think it's going to work

15 PSI is still to high IMO.
Been running 8 PSI for the past 10 years, never an issue.
Much smoother ride.
