Too much load capability with G rated tires?

Thanks for all of the input. I'm having Hankook DH01s put on now. Ultimately, I wanted the more aggressive tread of the DH01s. Yes, they are Fs instead of Gs, but I expect even on the front I'll never have more than the truck decal recommended 80 lbs and less in the rear. That gives a 15 lb cushion which is less than the 30 lb cushion of the Gs, but I think still plenty.
