had65want05 said:It's just a fad, like bell bottom pants, I would think. NASCAR uses 15" and they get around the track at 180+ MPH just fine. The 13 and 14 inch are harder to balance, so those are out. When you get into 15, to 17" there is plenty of rubber on the ground and they are at a good price for tire replacement. Just because soemthing is a fad, does not make it better. Personally, I think the super large ones look hiddeous. Why make your sports car look like an SUV? That said, if it lights your fire, go for it. I have seen some low rider cars with what looks like 12" wheels, or something. If they are happy, that is great. If ya own the car, do your own thing. The next thing ya know, sport car companies will be building SUVs

I agree for the most part. I have 18s (BBS RKs) on my '98 Cobra and I would have gone 17s if the same width and offsets were available. Cheaper tires and less road noise/ride deterioration being my reasoning. My other car ('03 330i) has 17s, and I didn't opt to get the 18s for the same reasons. The '05 Mustang is a different animal in that the overall height of the rolling stock is greater than before. The section height of the sidewall is going to be greater than the same size on the current car, so a larger diameter will be needed to make it look 'correct'. 18s look to be plenty big, with maybe an optional 19 on the Cobra. This is the first car I have seen that looks good with 20s(the concept), and this goes back to the wheel well opening/tire diameter.
