Pasalas are the best tires I've found. Long life, good ride, excellent flat resistance. Around here we ride on wide, glass/thorn covered shoulders, Pasalas TG/PT never let me down. If you're going cheaper, I have found the PerformanceBike Metro-K tires aren't too bad.

Low quality but they make up for it with the highest prices. Total waste of money, esp for commuting.
