whats the widest tire and wheel for 07 gt

larry....i'm running 18x9 and 18x10's on my 07' GT 265/35 and 285/35, i had these wheels on my 04' when i traded the car i was thinking these wheels will stick out co'z of the off-set of the 07'. springs came in Eibach sportlines, drop it, put the wheels on, fit perfect! no rub at all whatsoever, handles awesome w/ the wide wheel in the back!!!

hopefully this will help...

Wow! Great pics and great looking car, BREDn07. I really wasn't looking to change out my wheels at this time, although I like the look of yours, and I don't think my factory wheels are as wide as yours in the back, but if I could slip some 40 or 45 series on them, I'm wondering just how wide I could go before I run into a problem.

I had 285/35/18 on my 18" chrome factory bullets. 07 gt/cs fit super nice changed to 18x10 black deep dish bullets & 295/45/18.
