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.

The rear axle is only rated to 4050 lb unless you have HD payload.
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.

Does the yellow sticker include 150 pounds for the driver? Is my real payload 1277?

I get what you are saying, I think your estimate might be a tad on the high side, I forget if my truck weighs 6 or 7k, I think its 7K though and ive never split weighed it but im guessing the back is much lighter than the front which should allow for more payload at the rear, if you take you 2403X4 you get 9612 and subtract the 7K weight of the truck that leaves 2612 before you hit the tires weight limit if you could evenly disperse the weight, granted you have some wasted potential on the fronts, the key factor is the weight on the rear axle, but still the 1800 in your guestimate is way more than his 1100 actual allowed, which would be higher if he had max tow. But then lets say you put an LT rated tire on there, does your payload rating go up? and if so how much before the axle rating comes into play? Its a combination of a lot of factors and I dont know them all. I live close to a scale, ill try to remember to weigh just my rear axle next time i drive by it just for giggles, you got me curious now, haha!


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!

IMO the only way to truly know the answer to this oft-debated question is to weigh your truck.
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.... . .

IronJoce

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

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

I know that tire capacity is only part of the equation but since that was brought up that was the example I used.

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.

Thats what I would do. Just curious, whats your GVWR listed at on the door? I would go from that after you weigh the truck.

That has to be wrong. I have the 157" screw Lariat and my door sticker says 1582. What makes yours so much heavier?
