The 19" tire is "All Season" rated. The 20" performance tire is "Summer Only." So if you want an i3 "without the hassle" you simply get one with the more-common 19" wheels.
Yep. I rock all season tires on my (not an i3) car as well. They’ll never be great in the snow, but I live in an area where snow is rare so that’s fine.
I can certainly imagine the “bicycle” tires must not be very good at all in the snow unless they’re the specialized winter version!
