RT4WD tire pressure vs front rear preload?

Band Wagon
Put new snow tires all around on a RT4WD auto/PS wagon we just purchased last week and noticed the steering seems to be quite mushy. Granted these tires have less than 100 miles on them and the TireRack feedback thread does mention giving them time to break-in.
Added air to the front because they looked low, now have 36lbs in the front and 32lbs in the rear.
Can't really feel the difference, but it seems like it would be more correct to have both front and rear as close to the same diameter at the ground re: preloading the vicious coupler.
Questions:
Given that the front/rear gearing ratio preloads the vicious coupler by 1.7% will running harder tires in front affect it badly?
Is the preload making the front or rear try to turn faster?
What is the front/rear weight distribution for an empty wagon anyway, is the goal to have both sets of tires be essentially the same diameter or is the preload designed to compensate for the heavier front squished down tires thus evening out the the front/rear gear ratio?
Will running more air in the front tires adversely affect handling?
thanks,
Dave

Comments
also it might feel "squishy" do the the fact that they have a tall sidewall
what size tires are you accustomed to driving on?
Reason why i think so? Because if you had to be that precise on exact diameters, you would have to put air in your tires every time you filled up your tank and then let it out as your tank went lower, easiest way for peace of mind on RT's is to disengage the awd when you arent using it
I'd run them all at the same psi. Whats the recommended max for the tires?
