From @john glass:

I have a 2022 MY LR, "mfr'd" 1/22 w 19" Conti ProContact tires w Gemini wheels, which I run at 42 psi CW.  It rides fine on the highway, 27K miles, but is a quite bumpy on backroads, reminiscent of my old Pontiac Vibe.  Would a trade-up improve my ride (how much) or should I wait for the Juniper?  How about an aftermarket suspension & which one or kind (frame or air)?  Tires - 18", different mfr/brand (Michelin AS) have any noticeable effect? Don't want or need MS or MX.  Thanks for any advice.
