[s-cars] Do all 4 tires have to be the same?

[Tom Rodriguez]

I know that given our Quattro system we must run the same size tire on all
four corners, but do they all have to be the same make and model?  I
recently damaged the sidewall of one of my snow tires so it cannot be
repaired, and I have learned the manufacturer (Bridgestone) has discontinued
the model.  The other three snow tires are relatively new and are good for
at least two more winters.  Can I run a Bridgestone snow tire of the same
size but a different model on one corner, or am I asking for trouble?  I
hate the thought of buying four new snow tires when only one needs to be
replaced.
