uhm 225 is not wide... wrong thread
I would fit it on an 8... 7 ur maybe talking 215... imho... to really benefit from the full thread...
Edit: my dad runs 225/50/16 on a 16x6 lol.. sure itll work but yea it won't really be solid... he bought new 16x7.5 wheels though
(2lbs lighter than stock too :P).. and its for a non nissan car but whatever..
