I got the 28mm to fit, just couldn't air them up until they were mounted. There is probably 2-3mm of space left over. I had some fun truing the wheels to keep a good even space all around. I will definitely if the wheels start to loose true. I am thinking this weekend I may get brave and at least give it a test spin. I aired the tires to the 125psi sidewall max and will go from there. I just hope that I don't jump on and immediately blow out the tires, I would feel really bad and I'm sure the GF and daughter would say " see it is too pretty and tiny for you, give it to me."

I love my crosscheck, can fit 45's or more. I'm 235 lbs and run 55-60 psi on mavic A-719 touring rims with panaracer pasela tourguards in 700 x35. I don't race and use it for commuting, sometimes dirt as well. The ride comfort is really nice. Good for bumps, potholes and lousy Boston streets. I think 35's would be good choices for the larger sized riders, but need to get a bike that fits them. YRMV

Oh this is good to see...
At 285 + pack (from 10 to 50) I ran marathon plus (rear, 48sp chukkers) 38 over sidewall rating at 90-ish...
Below that it sounded like a cheap truck tire until about 3k miles. After that was ok down to 80's but tried to never venture lower.
Down around 240-245 now, good to know I have some serious safety margin!

I ran Terry 28-571 on Sun 36H M14A rims on a bike for several thousand miles at 330 - 350 lbs. I ran 110-120 psi in them, no issues. Then I ran over something in a construction area that put a 1/8" diameter hole through the middle of tread. At that time Niagara was not carrying the tires, and I decided that it would be cheaper to switch to 37-590 tires on Sun CR18 rims (36H front, 40H rear). The brakes had enough travel to for 571 (650c) through 590 (650a) rims. Now I am contemplating a 584 (650b) build on the same frame.

The Terry tire is made by Panaracer, it is effectively a rebranded Panaracer RibMo PT.

I'm 300+ so I've been riding 32mm tires. I recently damaged my rear wheel but am dropping weight fast and plan to upgrade bikes soon. A generous person in one of my riding groups loaned me his old "clyde wheels" and they were for a road bike. Custom made with what looks like 40 spokes in the rear. But being performance roadie wheels they had 23mm tires on them. They are just loaners so I'm not about to mess with the tires unless I have to but I've been riding on 23s pumped to 120. I haven't hurt the poor things but wow are bumpy paths bumpy on those things. Concrete feels like cobblestones
