The VW XL1, the most efficient production car ever made (limited run, otherwise Honda Insight takes that crown) calls for 115/80R16 tires. Or, in other words, very narrow tires with a large aspect ratio.

The Insight calls for 165/65r14, which has a similar diameter - I don't think such narrow tires were available when it came out.

The BMW i3 calls for 155/70r19 on the normal model, and 195/50r20 on the sport model. The wider, lower aspect tires result in a significant range penalty in EV mode.
