Had the same experience with the run-flats. Hated them. Was almost ready to get rid of the car. Have had 3 Lexus and this was first unsatisfactory experience. Replaced them with Michelin Pilots and can't believe the improvement. Handling, ride and noise dramatic improvement. Am now a happy camper.

Prestone makes a kit that contains an inflator and sealer. I purchased one ($28) and carry it in the trunk in the event of a flat. This is pretty much the same system that BMW provides with their M series cars which come standard without a spare and have regular tires, not run-flats. Figure if it is good enopugh for them it's good enough for me. Lexus should follow suit instead of having unhappy drivers.

AWJ replaced with Pilots. What did you do about a spare? Or are you traveling without one?
