Then one has to deal with the at cops in th shacks. Which many times depending upon the states, do not care about the tire, spring or Adel ratings. Only that you are below the 20k lbs per Adel, with no less than 20" of tire width per side to support the load, so you do not harm the roadbed ssurface, sub grade etc. You can have an Adel rated to 25 k per the specs shown earlier, but be over weight as you can only load the Axelrod and its components to 20k lbs.
Ive been pulled over here in wa st many times over my manufacture rated Adel capacity, I have yet to get an over weight ticket, as I am under my paid for license, and the max load per axel with out harm's mg the road bed itself.
Choose your poison in how and what to follow, too many rights and wrongs frankly.
