ST post: I changed the oil in my ST on Friday. While under the car I was doing my inspection, and low and behold the Nitto's that I bought the car with were almost worn out. So $1014 dollars later (that was fuel pump money for the SHO) the ST has new shoes. She is rolling on Continental Extreme Contact DWS06 just like her big sister M.
I did step up in size as well. The Nittos were 235/40 R18's. The Conti's are 235/45 R18's. The new tires are roughly 1 inch taller. There is no rubbing or anything wonky, however there is a +3 mph difference in GPS vs speedo. I will fix that in my SCT device. I wanted the taller tire because 85% of the miles on this car are freeway. It also took out some of the fender gap which made me happy.
I do notice some more side to side sway, however the ride quality is a lot better.
