I have a 2022 Aviator with the air ride on order. After reading this post I went back to my dealer today and test drove both the standard suspension and the air ride back to back on the same route (both 21's with 22 inch wheels). Although the air ride is not as smooth as my 97 Town Car, it is a definite improvement over the standard suspension. My order will have the standard (for Reserve) 20 wheels which should be even smoother. I have test driven Aviators in the past with both 20 and 22 inch and there was a noticeable difference there as well, 20 inch being smoother.
