I currently have Bridgestone Blizzak run flats on my car and may wait another month or two before switching to aerated tires, despite the rough ride that exposes even the slightest bump as though it were a major pothole. Having read the other postings on the site, I am going with either Michelin Pilots or Bridgestone Potenza RE960A Pole Positions. I also obtained the quote from the dealer about adding $900 worth of additional equipment for the spare, etc. and have decided that I am instead going with a green slime kit w/ portable 12V air compressor, placing it in the spare wheel well. These are available at amazon.com or at Wal-Mart. When I have the new tires installed, I will show the mechanic the various postings about adjusting the alignment - taking the negative camber out as much as possible, and setting the toe-in for the front and rear. Any other alignment advice for when the new tires are installed?

Thanks, the Michelin Exalto A/S sounds like a great tire for the SC430 and is top rated for ride quality and quietness. However, they don't appear to make these in the SC size of 245/40/18. Bummer. Any other ideas?

I have driven OEM run flats on my 2007 SC430 for roughly one year and have reached my limits in terms of ride quality. Clearly, run flats are not where they need to be in terms of ride quality and diminish the driving experience of a wonderful car. This spring, I am moving over to aerated tires and am also looking for a smooth and quiet riding tire. Like, Reyan, open to ideas other than the Toyos. ContiProContact Extremes? Michelin Pilots? Others. Thanks for your help.
