Yeah, as
Fentuz points out, tire reccos are rather pointless without knowing the kind of terrain and surface you’ll be on.
In the summer, ride hardpack dirt roads over rolling terrain, so file tread 700x 35c rubber work pretty well for that, but just as importantly, gives me the kind of paved road manners I want. Even if it’s only 10 paved miles out of 40 total miles, I just don’t feel right slogging down pavement on heavily treaded tires…too much roadie in me, I guess.
Come fall, winter and spring, I do go for some tread, and have ridden Schwalbe G-One 700c sucessfully. I’d like a set of 650b wheels for the racy gravel bike, though, so I can max out tire width for the float when its sloppy out. Whether I can swing the 650b this season or no, I’ll probably go with knobbies from Rene Herse because I really like the feel of their file tread tires, which I run in both 700c and 650b (on another bike; wrong freehub for the T-Lab’s SRAM AXS, though, so cannot share between bikes. Grrr!).
