Tires: matching sizes, audi a 4, rbt

Question
I have a '98 Audi A-4 and recently got a flat on one of the tires beyond repair.  The gentleman at the tire store said that because the vehicle is all wheel drive that all of the tires need to be exactly the same. He looked up my current tire and saw that it was not in stock, and had actually been replaced by a newer model.  So he recommended that I purchase four new tires, well of course he did.  After leaving I looked up the tire on the internet to see if I could find the old version, and I think that I have, but I wanted to make sure it is the right size- so that is my question- My other three tires are Bridgestone Turanza LS-H P205/60 R16 91H M+S, the one on the internet is the same except 205/60 R16 91H BSW, RBT will it work?

Answer
Jared,

This is a question you need to ask Bridgestone, but it sounds to me like you've identified a different tire.  The letter "P" in front of the tire size means it was designed to US tire standards and the lack of a "P" mean it was not.  That to me is enough of a difference.  

But the folks that know the answer are at Bridgestone.
