Interesting. As I just inflate the Schwalbe Marathon Supreme 700x40 to whatever the mood is. Usually about 45 front and 60 rear. And after about 2,400 miles on them last year, do perfer them to the CdlV in 650B. Those were good tires, but I didn't find them in the same quality league as the Schwable. At least for my riding preferences.
Again, that's probably just my preference and my weight. If I were to lose a lot more weight, things might be different. No matter, right now, 40 is about the narrowest tire in the lineup. Although maybe my 700C studded on the Hillborne are not so wide. But that bike hasn't been out yet this year. Weather too crummy. The differences in folks getting tires to fit in the Ram make me wonder if there are either rim issues involved or - and this is highly unlikely - one batch might be slightly narrower in the stays?
