I think you are in terra nova here, Joe.  Some of the BROL stalwarts may have done this.  Part of the reason for the ride improvement is the lower pressure required in the tubeless tire, but you don't want the lateral forces separating the bead, either.  Probably not a problem with those tires, though.  It's a change I have contemplated, in lieu of fatter tires, as those aren't readily available in 16" anyway.

I started a thread on BROL with the same topic as well, only a couple responses so far.  One inquiry as to PSI and another with a link to a velo thread where a guy had made the transition if your interested in reading it.

Buy the Schwalbe Ones, not the Pro Ones.

Just to revisit this topic, briefly -- I put tubeless Ones on the front of my SprintX back in July...  they definitely gave a smoother, slightly faster ride.  However, when one decided to lose its seal along the rim (why, I still don't know) while sitting in my car, it was impossible to reinflate it with a hand pump, and was just a mess.  Rhett at John's recommended using a compressor, for a faster blast of air -- which is nice if you're at home, but useless if you're on a ride....   I went back to the Duranos, but am keeping the Ones, and will probably use them WITH a tube, eventually.
 
If you're racing, and need an edge, it might be worth it...

I have been researching tubeless tires since watching the Tour de France this year. Everything I have found out leads me to believe it is too early in the development to putting them on my trike. Yes they are a soft ride due to the lower operating pressure. but re-inflating on the road is
nearly impossible. Have you ever had a flat on the road with a slime tube, no fun? Who wants to follow me on the road with extra wheels? New sealant has to be added about every three months to maintain pressure and rim seal. How much weight does that add each time? Side loads on trikes are much higher than diamond frames which adds to the sealing problem. Of all the roll test I could find the fastest tubleless was almost 1Km/Hr slower the a butyl tube/tire.

You might try what Darrell at PC&F calls an air pig, the tubeless tire setter, which you inflate to hold air, then can be placed in your car.  Check it out:  https://www.specialized.com/us/en/equipment/accessories/air-tool-blast-tubeless- tire-setter/131406

Still doesn't help when you lose pressure out on the road...   Smiley

You use CO2. an airzound bottle (with modifications) or airshot bottle to fill them on the road ..    Basically you pump that up and dump it into the tubeless tire

My tubeless experiment lasted almost two years. The roads I ride are so rough, I really wanted a better ride. I never got my Velocity A23's to reliably keep a seal for very long with any tubeless tire, so I built myself a set of ZTR Alpha 400's. When paired with Hutchinson tubeless tires, these are reliable. They also worked with Schwalbes. I used an Airshot to inflate the tires at home, but just carried a tube for the road. Using a tube inside a tubeless tire works fine, so is the quickest and simplest road repair, if you don't want to carry that Airshot beast on the road.
 
A 700 x 23 Hutchinson Fusion, run at 80 psi, lasted over 3,000 miles on the front of the F-5, the most wear I've ever gotten out of any tire on any bike. I never had a single flat on either of the two Fusions I ran on the front. But I never got anything to hold up on the rear tire. And when I got a flat, it often took a boot to make the tire work well enough with a tube to get me home. I never seemed to keep a good enough seal to get home with any leak on the rear tubeless. Half the time, the damage from the leak would be so bad, I would have to scrap the tire, and go to my spare to get home. I never managed a full month of riding on any tubeless tire without a flat on the rear tire. The last six months I ran tubeless on the front, I had given up and was just running a tubed tire on the rear.
 
Schwalbe Ones are faster than the Fusions, but didn't last as well. I also ran three Schwalbe Pro Ones (one was a warranty replacement), and never got 300 miles out of any of them, not even on the front of the bike. That's why I recommended against them earlier in this thread. They would quickly develop sizable knots on my rough roads, knots that would give a noticeable thump as I rode, and they flatted often, too.
 
As I mentioned earlier, my roads are rough. Many of my miles are also on highway shoulders which are full of steel bits from truck tires. So my experiences may not match yours. My A23 wheels are wide enough that I'm able to run GP 4000's on them at 80 psi without pinch flats. They don't ride quite as well as the tubeless, but not bad, and they're fast. They hold up well when they're new, but seem to lose their flat resistance over time, so I usually only get 1,000 to 1,500 miles out of the rear tire. But I think that's what I'm going to keep on running, at least for now. When someone comes up with a 700 x 25 (my preferred size on the rear) tubeless tire that's reasonably fast, but will hold up on my tough roads, maybe I'll reconsider tubeless.
