I have those on my car, they are not chromed, painted, or coated. they are a polished aluminum so as long as you maintain the polish they should look good forever(no peeling or flaking). As far as the width I beleive they are 18x8, Stock tire size was 235/50R18, One other nice thing i like about the wheels is no visible wheel weights and you can actually get to the inner part of the rim for that showroom clean look.
From their website:
"Note: For vehicles with 16" wheels from the factory: -installing 17" x 8" wheels, use steering stop 4R3Z-3932-BA -Installing 18" x 8.5" or 18" x 9.5" wheels, use steering stop 6R3Z-3932-CA

Nitrogen is a more stable gas, hence it's known as an "inert" gas.
Oxygen is more reactive (oxidizer). Air, as we all know, contains oxygen and as such, is also reactive.
Air tends to expand more with temperature changes so pressures go up and down more than nitrogen.
Because nitrogen is less reactive some say it makes your tires last longer.
I don't know about that, there a lot more factors involved with how long a persons tires last than just what they've filled them with.
Nitrogen is used mainly in the aircraft tires because if you have a fire in a wheel well, for example, and the tire blows, you wouldn't want to give the fire any more oxygen to use. The nitrogen tends to have a smothering effect as well if the tire does blow.
If you have ready access to compressed nitrogen by all means use it. It'll keep your tire pressures slightly more consistent.
But for everyday driving, you'll probably never notice a difference.

What is a steering stop, what is it for, and what will happen if it's not installed before changing wheel size? Someone told me about a steering stop awhile back but when I asked about it, no one knew what I was talking about.

You don't need them. They are a device that goes in the power steering system to limit the travel of the wheel from full left to full right, to keep the wheels from rubbing on the wheel wells on extreme turns. Just stop turning any further if they start to rub. I put 18-9' fanblades on my 6 with wider than stock tires, and I only rub if I reeeeealy crank it over, when it gets there I back off,
I know this thread is old, but nobody ever answered your question, so I figured I'd give it a shot.
What is the width of the Chrome 5 spoke GT wheels that Ford sells?
