Calculated payload

Add the weight of the driver to your calculation, not just passengers.

Factory GVWR on a pickup truck is not a number that's enforced by any DOT officer or weight police in the USA. What matters is what you have the truck registered for, and then only if you're hauling commercially.

It is your call whether to exceed GVWR, but from a purely technical standpoint, you are good up to RAWR. The 10k GVWR is so that the truck can be classified as 2B, which is for tax purposes and has no technical ties to the truck. Again, it is up to the owner whether to exceed GVWR, but you're going to find it difficult not to do with a decent fiver and an aux tank, unless you keep that tank empty. FWIW, most of our trucks you see with large fivers on them are running over GVWR.

tires are 1450 pounds max @ 75PSI each.

1450? At 1450, you'd be overloaded with an empty truck (mine had around 3200# empty RAW). If you have 18s, they may be around 3450#. Is that what you meant?

On the 2500HD, the RAWR is derated to 2x 20" rim capacity. Axles and brakes are the same part numbers as 3500HD SRW. Only difference is an upper overload that engages around 6k# RAW on the 3500HD; doesn't exist on the 2500HD. If you have 18s on your 2500HD, you have the same config that the 3500HDs come with - they don't offer 20s. So the only thing you are missing is the overload.

That was kgs. Correction: 3190 pounds each.

Here is a training video the explains how to calculate you tow ratings and you Payload Ratings for your truck.

Payload = GVWR - Actual Weight of Truck (ready for towing)

Yes, it's that simple but you do have to go get it weighed...

Unless you have a tiny fifth wheel or an empty aux tank, you will be over. Worry about your rear tire capacities instead.

You're "probably" safe going over GVWR as long as you aren't running commercial. 10K is an artificial number used to make it a class 2B vehicle for tax purposes. It means very little from a technical standpoint. That being said, the amount of liability you want to assume is up to you. 90pct or more of the 2500HDs you see pulling 5'ers are "overloaded". I don't believe that to be an exaggeration. The major limiting factor for a stock 2500HD is the rear tire capacity. If you have 20s, even more so. 6200# RAWR or you'll be over.
