If so, the wear on the very expensive rear tires will be alot with no option of rotating. Even with bringing the fenders in 5-10 mm, alot of wide rubber will be required to fill out those broad haunches.
This is a good point, and I had mentioned something about this in another thread awhile back. I would hope that GM will make it an option to have different tire sizes up front and in the rear for the reasons you stated, primarily I don't want to have to turn around and buy new tires every few months.
However, with 400+ hp, it will require some pretty serious tires to be able to transfer that power.
