When I test drove the LR originally back in Sept. it was on 22's and at the time I honestly thought it was pretty soft and smooth coming from 5+ years with Model 3 life on aftermarket 19's, first one was lowered as well.
I ordered my LR X with 20's and it's soft I guess, but the suspension setting matters a bunch too.
I'm usually in Comfort or Auto, but switching to Sport is significantly tighter, more responsive and harsher as yo would expect.
Also the ride height changes the harshness and rebound a bunch. I find myself sometimes going to Medium at times on rough roads just for added comfort, but on the refresh builds you'll default back to Low after 55mph.
