I was being a little cautious (not something I'm known for, when gravity is to my advantage) on my 32mm tires; I was getting bounced around a bit. He was riding cushy on huge tires and a suspension fork.
Overall, I think 35mm tries would be the sweet spot for me, at a little over 200lbs these days, but I might ride my '72 Nishiki Semi-Pro, which is already comfortably shod with 38's.
For 95% of this ride, fat knobby tires is just way overkill, IMO.
Beautiful bike. Oh yeah, I wouldn't use knobbies but 26 x 1.75 road tires. Why not keep the 38c tires? They seem perfect for the job.
