plus the 205-45-17 is exactly the same overall diameter as your stock 205-50-16.
why people use that size instead of the OE 215...which is about .6 inch larger.
I have been pondering the EXACT same thing:
16's or 17's? Ride comfort would be nicer with more sidewall. Something to consider in a daily driver.
But those SVT Euro wheels are so nice!!!
Another argument for more sidewall is that the tire will give you more warning (in feedback, or feel) of breakaway, as in extreme under- or oversteer.
Interesting question. I would like to hear more people's opinions on this one.
