I think you should change the tire size to one of these combo.

F 255-40-19 R 285-35-19

or

F 275-35-19 R 305-30-19

I prefer the first one since 2nd combo is way too much in my onpinion for the stock setup and power.
Generally speaking, if you over size the tire too much, you might get a nicer look, but you not only eat at your power but it can also tend to numb the feel of the vehicle.
