Have you got any of the 15" rims sitting around?  If so I would go with 
either a 195/65-15, 205/60-15 or a 205/65-15.  Just got the updates from 
Nokian and there is going to be a new tire; the RSi to replace the Hak Q 
in all but 10 tread sizes.

The 225/50-16 have a OD of 24.9" and a load index of 96; and a 215/55-16 
is 25.3" and load index of 97.
The 205/55-16 is 23.9" and a load index of 91.
I've got lots of the various Hak treads and sizes in stock now.
Going with a skinny tire on a 15" rim is the way to go if you  want foul 
weather function.

Good luck
