I run 285/75/17 on 2nd gen truck 2 in. leveling kit. I think the tires are 34 inches tall. NO issues. The tires are the Toyo MT

 

So a 315/75/16 is the biggest you can go without rubbing, or a 35" on a 2.5" leveling kit. I have 4" backspacing 8" wide wheels with 315/75/16 tires (34.6), and clear by 3/16" inch on the backside of the fender. With 35" Super Swampers, I hit by about 1/16in on the same spot, 10" wide wheels. With stock wheels and 315/75/16 and leveling kit you will clear just fine.
