I always put "C" rated tires on a 1/2 ton. Anything more is unecessary and to me too much. I would definitely be running the "E" tires at 50 psi minimum.
The noise you are hearing is probaly the pinion bearing. Very common when vehicles get around 100k miles! I just did an 06 F150 for a bearing noise.
I couldn't find any C or D in my tire size, so I just went with E, which is fine with me.
You may be right on the pinion bearing. I've got 108K miles on the vehicle. Going to see if I can get it in the shop this week before something breaks.
