Best acceleration is the smallest wheel that will fit around your rotors, probally 15". Auto cross people use small wheels and low profile tires. Best handeling and acceleration but not good for highway (as the diameter of the wheel is slower and higher RPMs needed for same speeds)
Everyone has their opinion but you have to find a compromise between speed and bling and budjet.
Forged wheels are lighter so you can get bigger wheels but they will cost you!
I think 17s are best for acceleration and handling but 19s are best for looks.
Do what you want as its your car!

See, I'm totally a noob on cars. From what I knew was the bigger the tires are, the faster you can run because the engine still makes the rod( not sure if that's the right way to call it, I mean to say the rod between 2 tires) rolls at the same rate, so bigger tires can go faster than small tires. That's what I thought it was. Can someone explain this to me? I got 16" , I thought my car can go from 0-60 in shorter time if I got 18"......duhhhhhhhhh

HP is a measure of how much weight can be moved a distance in an amount of time. For instance, 1 HP = 550 ft-lbs/s. This means 1HP can move 550lbs, 1ft in 1 second.
The heavier your car, the more HP required to move the same distance in the same amount of time. You have a set amount of HP. The larger rims equal more weight for the car. This means slower acceleration. The larger rims will give you a higher top end speed, but who will ever get the car going fast enough to notice any difference.

No...The HP comes from the engine. The 222HP quoted for the 3.0 is at the crank. So you are actually getting less than that at the tire, due to losses through the transfer of power from the crank to the wheel. The larger rims will only add weight to the car. The only way to add HP to the car is to make changes either in the efficiency of the engine or the efficiency of the transfer of power between the engine and the tires. You can look throughout the forum for a lot of mods people due to improve the HP. Things like a CAI (cold air intake) will improve power. There's quite a few different things you can do for this.
What you should always look at to determine acceleration is the HP/weight ratio. This is why a car with less HP could still beat you. It all depends on that ratio.

The weight of the wheel does more than adding weight on the car. Its all about rotational mass. A rough estimate is 1lb on a wheel is like 8lb in the car. (depends where the weight is located on the wheel, etc but lets simplfy)
This weight only affects your acceleration as it takes more to turn this wheel from a stop but once your up to speed it does not matter.
