[s-cars] One Flat Turns to Four

[Brian Pleet]

I blew a tire on my 95.5 S6 traveling between Calgary and Vancouver last
week. I heard a clunk, my aftermarket tire pressure monitoring system
started beeping and I watched the pressure drop. Unfortunately, that
stretch of the Trans Canada highway is the worst across the country with
hanging wire nets to catch the rocks tumbling off the mountain. I chose to
drive on, aware of the price of a ruined tire. Five km later I stopped in a
safe place and changes the Blizzak winter tire with one the summer wheels I
was transporting.

First I'm told you have to replace tires in pairs, to minimize imbalance
side to side. I ordered two replacements. Now I'm told that you have to
replace the entire set, one for four because the quattro system would be
upset by different tire radius. The blown tire was 7/32 tread depth, the
other side was 7/32 and the two remaining are 8/32 left out of a starting
depth of 11/32.

Two or four? Suggestions?
