I see them all over the place, these tall, skinny utility vans with the 12 inch tires/wheels. It seems like most of the manufacturers are making them now. Some companies don't make minivans anymore, but they produce these. Obviously, saying they have 12 inch tires and wheels was an exaggeration, but many of them do have incredibly small diameter tires and wheels. What's up with that? Most vehicles today seem to come with larger diameter tires/wheels, why are they so small on these vans? And what is the big selling point for these vans?
