What's your guess? Wheel size would really give us a good idea on overall vehichle size. These don't look like standard wheels to me, somewhat like upgraded wheels we would see on 5th gens with the RS Package or an SS.
I'm thinking these are 20 inches, which is interesting considering the biggest you can get on the CTS are 19s factory. Certainly aren't 18s.
This car has never looked ATS-sized to me, always a bit bigger
