Well of course you are right. The tire rack said to get the 17" asa ar1 plus Michelin Pilot Sport 225 45 for the front and 225 55 for the rear. Total price without the pressure sensors is 1663 which isn't too bad considering that 10-15k mi from now I'll have to spend 2k just to replace the tires that are on there now....plus finding a new tire for a spare will be a lot easier. Do you think these will look ok ? Do I need the sensors ?

I'd really like a softer ride and not have to worry about having the car sit for days if I get a flat.

If it makes the xfire drive more like a slk that's fine with me. I was looking for a used MT slk when I happened on the xfire to begin with.

thx,
