NHTSA says this about components of the GAWR:
"Gross Axle Weight Rating is the rated load-carrying capacity of an individual axle and wheel assembly.

Trailer axles are no different per Dexter;
Q&A *The Gross Axle Weight Rating (GAWR) of your running gear is determined by the lowest rated component in the assembly. The capacity of the wheel, tire, axle, brake, springs/rubber and hub are all considered.
That's really interesting. So, what drives the GVWR? I understand that registration grades play a role in some of the HD trucks, but what is the justification for the typical 1/2 ton?
My F150 Max Tow has a front rating of 3,450, a rear rating of 3,800 and a gross rating of 7,000. If the axles, combined, can both carry and stop 7,250, and the engine can pull more than twice that, why is the GVWR 250 pounds below the combined axle ratings? I'm not sure I see where that weak link is.
