205/60*13 is a pretty common size - or it used to be... so you should still be able to get name brand stuff, but you might not like the prices. but "no-name" brands are a gamble - you can end up with absolute junk or a good tyre - its pot luck.

Simex S8000 are about the only cheaper tyre I've ever driven on that I liked. They were actually very good. I don't know if they come in your size, but if they do get them. I had a set a few years ago and was very happy with them. I'll be getting a set of them for my R30 Skyline when its finally ready- $130ea for 225/50*16 for the Skyline.
