Geez, I did it again.
In my previous post I erroneously stated the Plus Two upgrade would be a 215/40-17 with an alternative of 215/45-17.
I should have said 215/40-16 with an alternative of 215/45-16.
I really should pay more attention to what I am actually typing.
Furthermore, the OEM combo for the SVT Contour is 215/50-16 so this would also work as a Plus Two upgrade.
