I would say your coach is balanced as good as you can get. When I weighted mine, I was surprised that I was over on my steer & drive & 1/2 the capacity of the tag. My vin plate shows little relationship to the individual actual capacities of the components.
Tire air pressure will be dependent on you comfort level lowering to the static capacity listed on tire charts. My experience has been as the ride gets better the handling does not.
