[s-cars] Tire size for '01 A4

[Taka Mizutani]

Calvin-
Not to be overly sarcastic, but how does that differ from what I wrote
below?

US spec cars switched from B5 to B6 in 2002- that's exactly what I wrote.
The reason I specified by chassis name is because in other parts of the
world, the model changeovers are not always the same.

The 2002 S4 is a B5 chassis- S4s didn't come out for the B6 chassis in the
US until 2004, although that's totally irrelevant to this discussion.
