with 4:56 and your power you may go into 4th gear with a 28" or smaller tire.
with 4.10's and a 305/45/18 ( little more than 28" ) i wan getting close to 4th with the 4l65e making a bit more power trapping in the 121 ish range

You will probably want a stiff side wall with such a heavy truck. Sidewall flex isn't as much a part of the game any more. It comes into play but the 30" will give you more traction then a 28 because of the bigger outside diameter.

I was looking and you might have to go with a full drag slick. They have a 33-10.5-16 so you might not be able to stay in a DOT slick but that isn't the end of the world.
