Gravel tires : 630's

My main rides these days are Rails to Trails and as such, the roadbeds are typically crushed stone, understandiing there is not many choices, what are your reconmendations....FYI: not changing wheel size....

By not wanting to change wheel size, you are pretty much limited to 271/4" tires, which in my opinion are not the best for gravel. Paselas are probably as good as any in that size. However you'd be a lot better off if you could go to 650B. Whether that is possible depends on your present frame being suitable, and, of course, how much you want to spend.

If you want something knobby there's the kenda k161 in 27x1-3/8 that is a bit wider than most 27" tires and has cross-style knobs on it... probably snag 'em off amazon for 15-20$. Personally I would go for the sand canyon for riding rail trails, the tread isn't as aggressive and it should be a lot smoother of a ride than the cheaper kenda tires. The only way I'd use those k161 is if I was hitting up a lot of muddy trails or something along those lines.

You can find 27 x 1 3/8" tires easily enough, for example the Swift Tire Sand Canyon (link). Note that these have a claimed width of 33mm on normal rims (so 2mm under nominal), so still a bit narrow for the riding you describe.

A slightly bigger tire (allegedly) is this one (link), but its a knobby tread and perhaps not appropriate for the touring bike in your signature.

FYI, I converted an early 80s touring bike from 27" to 700c and was able to fit 700x35 Panaracer Paselas with fenders. And if I wanted to remove the fenders I'd guess I could get to 38-40. While I value originality as much as the next guy, moving to 700c in this case is almost always the sensible move.
