007,
I've re-read your initial post on BimmerFest a couple of times and here's
my 2Cts:
-yes, different tires and different size tires can give considerable variance
in "feel", road noise, handling, turn-in responsiveness, etc.
But, I think the drivetrain/gear whine noise is coincidental, unrelated or,
is tire noise with that specific fitment and/or something else is amiss.
-the tire size rolling diameter "difference" is nil, for practical purposes,imo.
I've gone from punky-azz little 15s to Plus1 ++ 16s on my wife's crappy
Honda CR-V, with no problems; I've gone from oem 18s to big 132 staggered
19s on our X with no problems.
It seems like you are hunting for a problem or overly concerned about
the potential speedo diff: it is no biggie. As for "reprogramming/reclibrating"
the electronics, I must be missing something.
Slap on the tires, in the sizes within reason, you like, and go drive and
enjoy your X.
GL,mD
