I'm sure you meant 295/30/19 on the back.
What is the offset on the 9.5"? I am running 19x10F and 19x11R with 265/30/19 and 295/30/19 tires, respectively. I do not rub on a ZCP drop but probably will once lowered. I'm sure you will be fine.
If you don't plan on lowering the car at all I'd go with 255/35/19F and 295/30/19.
