I've seen plenty of reports that 22s do have a significant effect on range. I'm a bit baffled by
@F123456 response just above this one, though. I have a 2017 100D and 327 - 344 sounds about like what I got with 20 inch rims before lowering. I'm not sure what "highway+" speeds means, but it could be that I don't have regular long non-stop "highway+" drives. Unfortunately, I can't tell you what sort of % impact you might expect between 20 & 22 inch rims, but you could compare the fueleconomy.gov specifications on the two and also consider whether or not it has to do with how often/much who is driving each of them.
