Vredestein Sessanta is a good tire for the money and as The Laird says they are quiet and also very goods on rain from my own experience.
Regarding dimensions i would not go wider then 245 on a 9" rim. I prefer the stretch look it gives and good drivers dont need rim protection
Currently running 255/35/19 on 8,5 front and 9,5 rears on The S8 and there is just to much tire all over the place
So my choice would be 245/35/20
