[s-cars] 1. Do all 4 tires have to be the same? (Tom Green)

[tom winter]

One thing to do is check Craig¹s List for some used same model Bridgstones
as you have. If you are lucky you will find a replacement with wear within
the tolerance range. I was able to do this on my old S6 Avant with my snow
setup. Worth a quick search to see if you get lucky.
