That's actually a pretty tight tolerance!

If we assume that a 'typical' tyre has a tread depth of 6mm, then the
above suggests that the tread depth of the tyres must be within 0.3mm of
each other!

I believe the owners manual (at least in my 2003 A4) says all tires within
2mm (hope I remember the correct number). Otherwise the continual difference
in rotation front to back heats the oil in the Torsen differential causing
premature wear?

I was in Discount Tire awhile back and they wouldn't sell just two
tires to a guy that had a Quattro.

Don't kill the messenger, I am just repeating what the manager told
the guy ..... they (not sure if they is the store or the chain) had to
pay for a new transmission once because the tires they put on weren't
within the tolerance spec as written in the manual. Since they guy
was down to 6/32 on two and the new tread would be 11/32, they refused
to do it; they actually let him walk. The manager said, from now on,
their policy is to replace all four so they avoid that issue.

YMMV.
