I belive a big part of the Firestone debacle was that ford recmmended tire pressure towards the low end of the safe range in order to improve the ride of their SUVs. If people neglected to check their tire pressure regularly it could easily fall to an unsafe level. New cars will soon require tire pressure monitor systems partly due to this.
The Bridgestone RE950s are an excellent performance all season tire (they are what I have on my car), but according to consumer reports their snow traction is not as good as other tires they tested (I have snow tires). Also these are probaly not the kind of tire you would put on a Hyundai Elantra.
