I put Bridgestone RE960 AS on my SC. So for they run very quite, smooth, and handle very well. The tirerack.com feedback ranks these tires #1 for all all season tires from the customer feedback survey. The Firestone dealer put mine on and had no problems with the pressure sensors. Good luck.

The local tire shop I trust can do the Michelen Pilot Sport A/S for about $1200 installed. Continentals for $800. Are people getting decent mileage with non-runflats, or is the inner wear just part of the SC430? If they're all going to wear fast, I'm leaning to the $800 tires.

I would use a reputable shop and inform them about being cautious with the sensors on each wheel...hey that way you feel better and they are warned

As far as the alignment thats a job that is needed on these cars more than others, I had mine up to about 110mph today and alingment may have been an issue I will check that out and inform the board...

You can get a tire made by Michelin and not pay a premium. Buy BF Goodrich, and you'll get a tire made by Michelin for a decent $. I put BFG Super sports on mine, and they're a great tire. Relatively new to the market, so you may wait a day for your installer to get them, but you can get out the door for less than $700.
