Try this: http://www.discounttire.com/dtcs/infoTireMath.dos
If you go with a taller (larger O.D.) tire with no additional power to back it up, the car will become a dog. Try to stay with the OE diameter. Even a 1" taller tire only reduces the gap by 1/2" but will also raise the car 1/2".

The biggest tire I could find on tirerack.com without going to a truck/SUV tire is 275/45/18. This would be 10.8" wide tire and have a diameter of 27.8". This size tire would be the max I would go on an 18 x 8.5" factory wheel.

Thanks.
Do you know or have you saw 275/45/18's being run on a 07 mustang or equivalent?
Those would probably look good.
This sound more like something i'm interested in.
Is a 275/55or50/18 available?
Thanks again.

Once you get to 275/50/18s and taller, you can only get SUV/truck tires. This would not work well with a Mustang as they are designed for a much heavier vehicle.

I'm running 275/40/18's all around and I'll run 255/45/18 front and 285/40/18 rear when I have to change rubber. Those 275's tramline terribly on worn, rutted roads.

Thanks to all above.
I am in need of tires, so thought I would ask again to make sure since the tire shop where I will be getting the tires from will order them and will need the tire size to order. I will be stuck with the size I have him to order, so I want to be sure.
.
So here is the question " What is the biggest 18" tire I can run on a 07 mustang gt with stock 18" wheels "? By biggest, I mean just that, both width and height. I would like the size stated if possible, such as 275x45x18.
Not been lowered.
Thanks in advance for the information.

100% correct.
If it was me on the stocker wheels, I would go with the 255/45/18 up front and 275/45/18 on the backs. I would stay away from the 275's up front as it visually is not needed.

Once you know the wheel width, you can find the widest tire that you can put on it from the tire specs (i use tirerack's spec info). Also, any of the online tire calculators will let you compare the OE tire size to whatever you're considering and will show you the tire O.D. difference and speedometer error (unless you select a tire that has an equivalent O.D. which is usually preferred).

I have 275/45-18s on my 18x8.5" stockers and they fit and perform fine.
275/40-18 BFG KDWIIs.
Thats the widest I would recommend on an 8.5" wide rim.

Before those I ran 255/45-18s KDWIIs and wore them straight across
before replacing them. Proper tire rotation is the key to good tire wear.
