Sorry, saw your footer and couldn't help but comment...
22's suck on the X....we have both the 20's and 22's and now just drive with the 20' as the ride is so dreadful on the 22'. I don't just mean a harsher ride, which it is, the darn thing tracks all over the shop and not just on tram tracks...it's utterly horrible...
I am custom to harsh rides, usually only buying performance model cars...however if I was you I would seriously reconsider the wheel size, especially since the new 20's are so darn decent looking on the new X....
