Not sure about your math. A 225/60/16 will be roughly 26.6" diameter, 225/50/16 will be roughly 24.9". MN-12s have huge fender openings, IMO that size will look like azz on the car.
Check the load index on the tires too, you may have to put quite a bit of air pressure in them to have enough load capacity for the front as well. Typically a 225/60/16 will be a 97 or 98 load index, and the 225/50 will be 92, unless it is an XL tire. That's a difference of over 250 lbs. capacity per tire. Not trying to be an alarmist, just want to make you aware ...
