DAY AND NIGHT DIFFERENCE! FAR quieter, FAR smoother; immediately noticeable.

Known road imperfections and minor manholes now unnoticeable. Car absorbs all the way a full-sized luxury sedan should. I've driven in Comfort since new, which almost seems too soft now.

That said, not sure if it's the tires or because I returned a loaded 435i M Sport loaner [that I drove in Sport], but steering now seems a bit less precise. Not numb, not spongy, but less precise. Not wandering, but not sure how else to describe. Could this be because the tires aren't broken in yet? Can anyone confirm if this improves in a couple hundred miles?

In sum, happy for now!

Two more points:

Run flats are almost double the weight of conventional tires(!); upon new tire drop off, recouped one undamaged run flat, and the weight was surprising!

AND, saw a 435i Individual in the showroom and thought the leather weave on the doors was awesome; very Bottega Veneta!
