just got a '11 G37s sedan and it doesnt have the normal enkie split spoke sport wheels. mine has the 18' 9 spoke wheels. i looked on infiniti and it shows the specs being 18x7.5 and 18x8.5, my question is what size tire can i fit on there that wont look funny? i want to put NT01's on but the sizes jump from a 245/40/18 to a 275/35/18... that would be too bubbly in back right?

 

Yes, do 225 and 245.
