Currently it has 285-75-16's on stock rims with no clearance issues at all.
If you have the Off-Road Edition and already have 285's on it, there is no need to do anything to the truck to fit 33's. Go find a tire size calculator online, convert the 285 size from metric to imperial and you will see why.
Don't bother with the 10" rims. You can safely run a 12.5" tire on a 7" rim. Your factory rims will be fine. A 10" rim on a 12.5" tire will push the sidewalls out and weaken the bead. The 10" rims most likely have less backspacing (like most aftermarket rims), which could actually cause you to have interference issues with the inner fenders if the wheels are set out too far.
