Larger wheels screw up quattro?

["Rob Andrews" <rob@smu.edu>]

I was out looking for some car audio stuff today and the guy started talking
about my a4.  He said he didn't get one because one of the audi techs told
him he has seen problem with cars with quattro getting screwed up because
larger wheels were put on them.  I told him that I doubt it.  He said it had
something to do with the computer control but I told him there was no
computer control for the quattro to speak of.  Anyone else heard this ever?
I know it sounds crazy.
Later!
