Terry,
Thanks for the info and nice to hear from you. I've been away from the boards for a while as life just keeps me busy. But now I'm getting to relax with my 8 again.
I've done some inquiries to the few wheel companies that make 20" and some claim that you can run a 30 series tire on the rear and 35 series on the front. I know that increases the overall diameter, but other than the speed sensors, what else can be affected? I heard one enthusiast say the 20" are too much load on the axle. I beg to differ if you are staying with the same over all tire diameter.
I still haven't had a chance to install the chip you gave me. I had to fix other things and been caught up. I even sacraficed upgrading my 8 with a nice sound system and touching up parking lot bruises (those inevitable dings) to get my wife an 02 530i (Welcome to the family!) and now matching cars.
To make a long story make sense (or atleast stay on tehn topic of wheels) I'm giving my wife my Breyton Magics and now looking for wheels for my 8.
Signing off for now,
John P.

Diameter of the tire is important on an 8 too.
Sensors at each wheel and in the differential send speed signals to the computers. Standard answer is within 3% of each other front to back and within 3% of stock diameter on the rear for the speedometer accuracy.
18 inch wheels need 35 series in the 265 to 285 width ranges
19s need 30s and 20s should run 25 series (IE 275/25 x 20)
That isn't much protection for the wheels from potholes!
