Hello and welcome to the forum!
Ya the stock wheel will work actually with less rubbing than a wider tire. However the only downfall is you'll have to crank up the torsion bars and get the truck aligned. You'll also have to trim the valance a bit. As BigRedChevy said it will hurt your mileage with that big of a tire. On my 06 it went from 20 highway to 16 and 16 town to 13.
For tires I just went down from a 285 to a 265 (due to mileage) and bought a Nitto terra grappler. Im real happy with the tire they look aggressive but dont have much road noise and handle well.
