Here is a night pic of my ride with the Konig Prophets

The fronts are Wrapped in Yokohoma AES 100's with a good amount of tread left 205/45 ZR17

The rears are wrapped in Continental ContiSportContact's with alot of tread left 215/45 ZR17
( Just got these Mounted and Balanced, BTW the ContiSportContacts are Focus SVT Tires)
Although the tires are different sizes, there is no noticable difference and the treadwear an all the tires is even! NO off camber or under/over inflation, from what I can tell.
Check out the other pics in the post for what the tread looks like.
