Does increasing rim size affect the acceleration?

Yes, I agree with that point. BUT I was refering to the actual speed thru the gears. 2nd gear now feels a lot faster now. 3rd also flows quickly.

i went from oem 16's with 205-55-16 tires at 42.5lb/corner on the vibe gt today to trd edition (m-theory) matrix rim 17's and 215-50-17 at 47.5lbs/corner today and didnt notice a discernable difference in acceleration (nothing terribly detrimental, that is)

but my cornering grip is UP, finally

Hi, guys. I want to put 185/65R15 for winter.
Problems will not be turning?
Friction of rubber on the back.
