Appx 2mph difference from 205/40-17 at 65mph. And as the tread depth decreases, that difference closes to less than 1mph. Not enough to make a noticeable difference IMHO...
Doesn't seem to hurt power on the butt dyno. I couldn't decide between 215 or 205s.
Plus the extra side wall helps cushion the ride a bit.
I just got mine a week ago. I'm riding on stock suspension and wheels and went for 205/45's. All I can say is wow... what a difference a good tire that's 13 years newer in design makes. I know these are the re-branded Bridgestone RE0S03's, but they just destroy the RE050's. That's a tire that Tire Rack was doing tests in the early 2000's by the way. 140 treadwear is awful, but I would have been able to eek out a few more months on mine if I didn't get a nail in my tire. The repair started to leak, so I knew it was time. I couldn't be happier with these amazing Indy 500s. I have about 300 miles on them and they are brilliant. I read through this thread and they are still better than I could imagine. On a stock height, stock suspension car, the tires fill the gap perfectly, and the design looks amazing, especially with some tire glaze!
After about a day I really notice how quiet these tires are. The taller profile absolutely sucks up all the old bounces and issues the stock tires had. Because of the reviews, I'm biased to think that it's not just the taller sidewall that makes these tires feel so much more plush. Plus, even with the taller sidewall, they ABSOLUTELY corner better. The car sticks, and you can really feel how much stiffer the two-ply sidewalls are on this car. After 26K miles on my 2016, I was starting to get a little tired of the ride quality, and the tires wearing really increased the amount of wheelspin with my lightly modified car. I can't even break the car loose on these new tires, literally everything is improved. I'm upset there's few high-performance 205 choices in 17 inch wheels, but if you stay on stock height suspension, this is a perfect tire. Can't recommend enough.
I lusted after some Pilot Super Sports in the same size, but $88 a tire or whatever vs. $155 a tire on Tire Rack.... this is a no brainer. The PSS is NOT almost double the quality tire.

Yes, I know. The worn tires were new at one time also. I believe that the true comparison should be based on that instead. In any case though, the odometer reading won't change much between those sizes. I think a larger difference will be seen in the mpg reading since it's a bit more sensitive to small differences.

With the ST, I would not think you would feel any change by the slight tire size change (and by the reviews here, will feel vast improvement in ride and handling with good tires)...
^^^I could not give a CRAP about odo/speedo readings being effected, but rubbing/scraping/gouging brand new tires because they are too tall is something I cannot/will not tolerate.
Granted, the sizes I would want to use (215/45-17/225/45-17) are MUCH taller, and therefore MUCH MORE rub-prone (even at factory ride height/on factory suspension) than the 205/45-17s being discussed above. ;)
