What's your bike+rider mass? 110PSI for a 28mm tire is very high, I'd certainly expect it to be harsh.
My bike+rider mass is around 200lbs on my bikes with 28mm tires, and I run the rear tire at 85-90PSI for most pavement.
and they have zero tread. This ride in Spain will have about 10% hard-packed dirt road/trail.
Are you sure you need aggressive tread? Most hardpack is a good use case for road tires.
Schwalbe has this HS 348 model in 28, 32, 35, and 38--all of which would work on my rims.
Would they clear your brakes/frame/fenders? Rims are the easiest part of tire compatibility.
So, my questions are: does anyone cycle tour on 28s or 32s , or is that masochistic and insane?
Depends on the sort of tour. I've done lightly-loaded paved touring on 28s and been fine. I even survived a little bit of loose gravel, although that was less than ideal.
That's because that's all the bike will clear with fenders, though. Nothing wrong with going super wide.
