lol man ive been trying to tell you.. what width are ur wheels?
but i dont think you need to put a stretch tire on ur rims, you may just invest in some eccentric bolts, and add some camber. Or try lowering it some more, and see if you get some more camber out of the rear.
i think the g35 wheels are what 8" wide? dont think that will really do much with a 225..
