I have 18x7.5 all around on my car.. (guy before me bought em, didn't stagger i dunno why) anyways i have 225/40/18s all around, can i just run a 245 in the rear to get the stagger effect? or that + a wheel spacer? whats reccomended?

You should be able to just put a 245 on back, but you should post up the offset of the rears just to make sure they arent so extreme that a 245 would rub.

With 225s up front, 255s should be at the back, but without the offset, who can say? Also, a wheel spacer will only make things worse.

a 255? hrmm i dunno the offset of the wheels b/c i didn't buy them nor is it printed anywhere on the wheels...

I just checked the wheel fitment guide stickied at the top. You can't put a 255 tire on a 7.5" wide rim. The best you can do is a 245, so you'd have to live with that. The fronts then should be 215s but that's just the way it is. The car will be just slightly more tail happy but you'll learn this new limit.
A 245 tire on your existing rims will stick out another 10 mm from where your tire is now. Go see if this would create any problems for you. Since you don't know what the offsets are, you'll have to just "eye ball" it.
