I got the standard tires that come with the luxury line - sorry not sure which ones those are.
One things I've begun to notice (I've only driven about 200 miles so far) is that the vibration seems more pronounced on certain roads. So, for me, it only happens around 40-55 (rough guess on speed) and is significantly more pronounced on certain roads than others (although the vibration is there at those speed on all roads). It is very strange. It makes it feel like I'm driving on extremely bald tires and/or a car that badly needs a front end alignment.
