bayareawheeler, three flats just like that? Something's wrong there. When you changed out the tubes, were you very careful to check for whatever caused the flat? Crazy getting three flats like that! If they were all pinch flats, new tires may be the least of your worries (maybe your rim is toast?).

No commute this morning for me. The rear wheel on the the Dahon is being rebuilt at the LBS. Should be done in time for the commute home (this shop is closer to work than home) so I brought my bike gear with me on the subway.
