Exactly - bicycle tires.

Perhaps the parent meant to suggest https://www.bmwblog.com/2015/04/04/bmw-i3-winter-tires-revie... for the winter. At least according to that review, using the winter tires would have been better in the snow.

Of course if you’d rather run all-weather tires without the hassle of changing from summer to winter tires, it seems like the i3 is a bad choice.

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!
