Yeah I am rolling on higher volume, softer tires. Currently have smooth 44mm but have ordered some 42mm knobbies that I have on my other bike and found they roll adequately on smooth pavement.
Current tires are 44mm, extra soft wall
This is what I run on my Trek FX, and have ordered a set for the 520 as well (42 mm wide)

And part of that is avoiding threading the chuck onto the valve stem too tightly. I have used a thread locker like Loctite on the threads on some of my removable core presta valve stems, but if you try that be very careful to avoid getting any thread locker in the check valve, as that might prevent the valve from seating firmly.
So I am very new at this, and perhaps tubeless is not right for long tours, but in Arizona, tiny thorns are everywhere. You don't have to offroad, they are there even on the cleanest suburban road, and I had some flats out of the blue when I started biking in March. So one either goes extra stiff/hard or tubeless. Did not have any flats since I converted to tubeless. Interestingly, when I swapped out one set of tires for another (both tubeless) and ran my hand on the inside of the tires just removed there were several thorns penetrating through the casing, not visible from the outside, yet I did not experience a flat.
But when touring, I suppose it's prudent to carry some tubes for a quick roadside fix.
Thank you for the tip on Presta cores -- I do run removable cores, to be able to pour the sealant. So that's a level of complication I am going to have to get used.
