TV Payloads ???????????????

I have a ford 2016 f-250 powrestroke.
My axle ratings are
rear gawr 6100 lb
LT 275/70R18E 125/122r
65 psi
front gawr
5600 lb
LT 275/70R18E 125/122r
65 psi
adding the two together gives me a total of 11,700 lb of gvwr capability.
stated payload on door sticker is 2300 lb

My gvwr is 10000 lb.
My tires are rated at 3640 lbs at 80 Psi
If I increases my tire psi to 80 psi ,can I then safely increase my payload to 3000 lb or 700 lb above door sticker.
The tires and axle ratings are clearly capable of handling it.

Please explain your reply yes or no.
Thanks
Tire guys feel free to chime in.
If I am correct in my thinking the 10000 lb gvwr is due to the 65 psi
inflation and not because the vehicle isn't capable of a greater gvwr at
higher tire pressure.

Thanks

How much does your truck weigh? I had the gas version of that, the payload was 4000 lb.

Leave your tire pressures alone for purposes of this discussion. Tires are just one element. There is also the wheel rim rating, the axle rating, and the spring rating. Your axle ratings are based on all of those, and consider the recommended tire pressure.

Your two axle ratings don't add up to your gross vehicle rating, by design. That is because the vehicle designers didn't know where you were going to put your payload, more to the front of the bed (loading the front axle more) or more to the rear (loading the rear axle more). Your GVWR is still your GVWR.

If you are not a commercial carrier and subject to federal laws about GVWR, you can decide to load your vehicle over the rated GVWR, but not exceeding the axle rating for safety. Some will disagree strongly with that, and any time you carry more load you need to be aware of the need to drive with consideration of your load and conditions, but GVWR is not a magic number. The manufacturers will put a smaller GVWR sticker on many trucks just to get under the tax rules related to GVWR, and not change the vehicle. If you decide to exceed the GVWR that is your decision. I wouldn't recommend you exceed the axle or tire ratings under any circumstances.
