The BMW i3 takes an odd tire size. They are really tall and skinny. Tall for looks, and skinny for efficiency. As a result, there’s a much more limited selection of tires. If a person was to find wider tires and rims with the right offset, there would be more tire selection. But then the tires would stick out the sides. To resolve this, add some wider fender flairs.
So, how about it - a widebody BMW i3? Terrible idea. Probably. But still an entertaining thought.
