With the wars going on between the big three in who has the Best In Class Payload it would easy to up it to the axle ratings if it was safe to do.
By the way I did just make that up, I ask that question on tour of the Ford plant and that what they told us.
Not sure we may be thinking the same thing when we say static load. Are you saying the GAWR is the weight the axle should experience at most while hitting bumps down the road? I am saying you can put that much weight on them while sitting still. The general public knows nothing about the different concepts, so manufacturers would never base their ratings on that. Anyway...
The sum of GAWR (front + rear) will always be more than the GVWR. If their sum equaled the GVWR, the only way you you could legally achieve GVWR is if the load was distributed EXACTLY among the axles according to their GAWR.
The GAWR is often determined based on their (the rear/front end, axles, springs, etc) ability, independent of the vehicle it is going in.
In essence, the GAWR is based more on science (actual ability). The GVWR has many more factors... some political.
ALL of these ratings have a lot of safety built-in. Based on what we used to haul and tow in the 60's and 70's (we being people in general... not me specifically), these trucks could haul probably 50% more than their ratings and still not break down.
