Yes and no. No because tongue weight is part of payload. OP is going to be maxed out on payload with 460 lb tongue weight. Therefore his legal towing capacity will be about 4000 lb, possibly only 3000 lb.

You need to take into account the weight of the truck on those tires too. So each rear tire can hold 2400 pounds which equals 4800, now subtract the approx weight of the rear end of the truck, on a crew cab I would guess close to 3000 pounds. That leaves only 1800 pounds of extra capacity for payload. Im not sure how its worded in the 09+ manuals but according to my 05 manual going from 18's to 20's automatically reduces the payload by 500 pounds.
Therefore the payload is not limited by tires attached to the axle.
Fortunately 100% of payload isn't pressing down on the rear axle alone, especially the stuff in the cab, about half of the in-cab weight would actually be on the front axle. Note that I didn't calculate that, it is just a rough estimate.

EDIT: Ok, i didnt know the axle rating but it was posted as I was typing, so that answers my question about that. I knew I was right about the tires though, lol!

GVWR - the weight of the truck = available payload. Simple as that. The 150 lb question become irrelevant.
You're definitely on the right track because you're accounting for your bedrug, etc. Everything counts against you. Audio upgrades, bigger heavier wheels.... . .

OP, the payload on the sticker includes a 150lbs driver. It's not much but in your case every lbs counts ;-)

Rear end is about 2400lbs and my payload is 1895 with 20in P rated tires. So, maybe in 2005 this was different but today payload is the same with 18 or 20in wheels

Thanks for the advice. Sounds like I need to find a scale. I'll put the wife and kids in the truck, hook in the WD hitch to the receiver, put the WD bars in the bed and weigh it. What ever I have left is what I can spare for tongue weight.
