Anyone have any experience using the Larry Tire?

Looks like it would be in between an endomorph and a Gazz…
Larry is an endomorph with teeth. Same casing, more aggressive tread.
I would love to try one out but my frame does not have the clearance.
Yes, I’ve ridden the Endomorph a few miles and found that it really is a crappy unicycle tire, but I’ve been waiting for the Larry and I got mine Thursday and installed it on the Large Marge rim on my Surly 26er.
I tried it on a couple of short rides and I have to say that its . . . . . orgasmic! I don’t think I’ve ever gotten hard over a tire before. HUGE difference between the Endomorph and the Larry. Larry has the same pogo stick like “gush” that the Endomorph has for some great bouncing down stairs and big drops, but doesn’t have its handling problems and flat tread profile.
At 25/30 PSI Larry feels like any other unicycle tire - really. On the road, no road crown issues - it goes where you steer it. Backing off the psi down to 15 PSI, just a hint of its older brothers “tractor-tire” feeling returns, but you are having so much fun riding over everything in your path that you quickly learn to ignore it. After 5 minutes, you’d swear you are on a 29er . . . with a suspension.
I also weighed the Arrow 3.0 tire that I just removed and found that Larry shaves 10 oz. off your wheel weight too.
For those of you that suffered through the Endomorph tires, its worth the $100 upgrade to Larry and did I mention that it goes where you point it, without complaining -on street or off road.
I posted some fat-tire porn pics, complete with black-cock-and-ball for those interested in such stuff.

Is it possible to assemble the Larry tire on a 47mm KH rim or must it be the Large Marge?
And what is the maximum permissible pressure for the Larry?
47mm are OK, kaiser4racing rides this setup at a rigida rim as you see here
its the second from right the first is larry - LM rim
max pressure is 2bar - but you won´t need such a high pressure.
Could you please expand on what you mean by ‘OK’? 
Do you think it would fall off the rim or be unstable on a KH rim? Thanks.
High Intensity Bikes http://www.highintensitybikeshop.com/ recommended that combination for the front wheel of a bike I built recently using one of thier custom fat snow forks. They said it would handle very similarly to the LM and Larry combo and be a little lighter than the wide Surly rim. They didn’t have report any adverse handling issues in snow, ice, sand from this set-up. I ended up not going this route because the 47 rim would have been too narrow for the Maggie rim brakes I planned on running up front. Pic is pre-installation of the maggie brake mounts.
Some fatbikers actually prefer using 47mm rims for their front wheel to give the tire a rounder profile.
Skinnier rims would give you faster steering but not as much float or low pressure stability.
low pressure stability (sidewall support) is the reason why most unicyclists like wider rims than bikers.
Now we have the Larry. We still need the Moe & Curly Surly!

OK = okay
it works very well!
