Tossed on the 19" staggered winters. There is something to be said for unsprung weight. My summers are the staggered 20" with run flats. The 19" non-RFT make the X5 feel nimble. Steering isn't as heavy, acceleration much better, softer ride with the new tread and taller sidewalls. Road noise on pavement at 100km/h+ is noticeable, but I'd trade that for the traction any day.

Splurging for an alignment at the dealer tomorrow morning. We'll see if I can get them to pre-load it and follow my instructions for the rear camber/toe. I'm bracing myself for a wonderful experience. I'm sick of the hack, lack-lustre alignment shops that have touched the X to date. Stay tuned.....
