Softer than Comfort

I've improved ride quality significantly by doing the following:
I've noticed my ride tends to get harsh despite selecting comfort mode. What seems to make a significant difference is switching to Lift during slower speed driving and then after a several min of full Lift mode, switch back to Auto or Comfort. Not sure if the air suspension simply has more air in the bags or the dampers become more responsive, but the ride improves quite nicely. Not mushy or harsh, but nicely compliant with good road feel and stability. Just the way I like it.
Perhaps this is an early sign of the air shocks failing (87K miles), so until then this trick is working very well for me.
Anxious to hear if others have a similar experience.
Personally, I can feel the difference between Comfort and Dynamic immediately and its much more of a sense in the seat or your core than anywhere else. But there is a difference without doubt. My passengers claim they may feel something but it rather vague. For me it obvious but I have the wheel so that may be the difference.
Also, running factory 19", with Sport Suspension and lowered about ~10-15mm via Ross-Tech, this combination will make the ride stiffer (harsher) than factory or non-sport set ups.

Just to throw this out there, plenty of talk about failure of the airbag part of the strut assembly. Does the possibility of the strut (dampening aspect) itself failing to perform come into play here? 60,000-80,000mi out of a set of struts seems to be the norm.

I am told no
I have read the shocks do not wear out. Have replaced activevshocksvon the front end of two Suburbans.,The Delco shocks definately wear out around 100,000 miles. These may last longer.

I know this is obvious but tire pressure can make a big difference in ride. Tires inflated to the door label "full load" PSI will provide a harsher ride than if set to the "normal load" PSI as recommended in the manual. I've found this to be true on all my cars, especially in my air suspension allroad where the difference seems to be even more pronounced.

Pressure inside air bags depends only on the load and stays same for all height settings for the same load. So, air springs are stiffer when there is less air, lower setting.

If you notice a ride quality difference then your system is working normally. However you mention that you have the tyres inflated at close to max. That's your culprit right there. Why do you need them so hard? The max pressures are for if you regularly carry 5 people, a trunk full of luggage and/or spend long periods of time at high speeds (I.e 100mph+). For normal use the pressures should be much lower and as per the info inside the gas cap cover. For 18" "normal duty" it's 33psi front, 30psi rear. Heavy duty is something like 38F/42R. I tried it once and it really killed the ride!
I'll have to look to see what the recommended 19" pressures are.

Most cars have different recommended tyre pressures for optimum ride and handling for different load and speed duties. You should set your pressures for the conditions you usually run the car. How often you want to adjust them is up to you. For me I run them at the lowest recommended as usually only 2 or 3 people and no luggage in the car. If I go on a road trip with a car full of people and luggage then I will up the pressures as recommended.
However in the USA since the Bridgestone/Explorer debacle manufacturers generally recommend one higher pressure to cover their asses.

I actually started inflating them to max because I was noticing some oddness in the ride quality with them running lower. It went away when I inflated them to max. What I find strange about this car is that they have different recommended inflation levels depending upon who is riding in the car. I would expect the car to have an auto inflate/deflate feature for that. Do they expect me to stop at the filling station to adjust my tire pressure every time I bring my family along?
