At 19K miles I had about 1mm of thread left on the 19in original rear RFTs so I had to make a decision whether to change the two rears only with stock RFTs ($920) or change all 4 to non RFTs. I went with Michelin Super Sports.

Pros:
1. These will probably last longer by about 10-15K miles
2. Ride seems slightly smoother
3. I also notice less slippage when accelerating and crossing lane dividers
4. The car looks nicer with these on the 19in 313s.

Cons:
1. Slightly increased road noise
2. Car handles nearly as good as with the RFTs. Since the RFTs were stiffer tires it seemed like the turns were slightly crisper, and now with the Super Sports on I am noticing a bit more roll... But this is not a significant factor.
3. The car did not come with a spare/jack so this may be problematic if I have a flat.
4. All fours cost almost $1300

Any thoughts from members who made this particular switch?
