for a very inexpensive tire, I'd definitely recommend the Kumho Ecsta AST. 50 dollars per tire is a price that cannot be beat when talking low profile tires.

400 treadwear, great responsiveness, heavy stiff sidewalls and 50k miles if driven carefully.

Here's a link to reviews, prices, and ratings for the tire.

Good luck!
