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?

I went with the Bridgestone tires and had my tire guy read the alingment threads here and adjust accordingly. I have not yet resolved the spare tire issue yet. I do a lot of backroad driving and having the donut spare could be a peace-of-mind advantage. I would like to hear from someone who has given up on the runflats and how they handle the spare tire issue.

I am also looking to replace the run flats on my '06 SC430. There are a lot of useful recommendations to choose from. For those that have made the switch, I have a question. What about the spare tire issue? Not worry about, get the 12v air compressor and a can of tire sealer? The spare tire kit from the dealer is now (1-14-08) $900, which includes everything color-coordinated in Lexus fashion. The same dealer can get the spare rim for $135 and the donut tire for $150. A jack form Pep Boys for $40 should complete the set.

Any feedback on these options?
