32 and preferably wider than 35.
Shooting from the holster, I'd say my
prefered tire size is 622-40, 622-42, or
622-47.

Methinks they are the same as 28x1.50,
28x1.60, and 28x1.75.

I think you are right:

47-622 28 x 1.75 x 2
47-622 28 x 1-5/8 x 1-3/4 700x45C 28x1.75
47-622 27 x 1.75 700x45C
42-622 28 x 1-5/8 700x40C
40-622 28 x 1-5/8 x 1-1/2 700x38C

These digits BTW are simply what I have found
on tires so there is no attempt at normalizing
the English sizes. It seems sometimes they say
1-3/4 and sometimes 1.75.

I also have these:

37-622 28 x 15/8 x 13/8 700x35C
32-622 28 x 14/8 x 10/8

Perhaps just lack of
standardization/normalization behind those
"more than 8 eights" fractions...? Some of the
decimals seem to be unexpressable (cleanly) as
eights or sixteenths tho?
