I just stopped in at Green & Ross today - they currently have a promo on where you buy 3 tires and get the fourth free! (For ones in stock)
Well, I ended up buying my snow tires there. I was going to wait to get them from my Lexus dealer, but I phoned them and there was no way they could come even close to this deal.
So I bought a set of Michelin Primacy Alpin PA3's that were in stock in the factory size of 215/45R17. These tires are low rolling resistance and are a perfect match for the CT.
I ended up paying only $164.62/tire net (their regualr price was $219.50/tire). Too good of a deal to pass up - it ends Saturday.
Come winter I'll have my Lexus dealer install them on the factory rims.
