Nittos on 18" Bullits?

Remind me...I searched but surprisingly did not find any threads, although I'm sure I've seen at least one. Is there a 555R that will fit on the 18" Bullit wheels? You know, the ones they have at MustangTuning.com and elsewhere, very common. The wheels are 9" wide, and Nitto's chart states the 305/45 as fitting a 9.5-(10.0)-11.5 and the 305/35 as fitting 10.0-(11.0)-12.0. I've heard the Nitto's run narrow, so would one of these be ok for the 9" wide Bullits?
