I've been quite pleased with my Bridgestone RE71-Rs. These are a streetable r-compound tire which I can drive to and from the track as well as having a sticky tire on the track. They are directional, which means that they can be remounted on the opposite wheel giving longer tread life, especially important if you run often on the same track, be it clockwise or counter clockwise. Surprisingly, I found these tires through Costco (Canada) at a good saving!
On the other hand, if you are just starting out on the slippery slope, you may be well served by a set of Michelin SuperSports. There's lots to be learned on a decent set of street tires!
Have fun!
