Street or Track tires?

I am presently looking for tires and wheels.

But first, I need to find a tire that will allow me track and street driving. I know my tire size will either be 225-40-18 or 235-35-19. I am thinking the Bridgestone Potenza RE-11 may be my best choice.

[UPDATE: Nov 26 2010] I think I will buy 2 separate sets, one for looks, the other for track usage. I will resume my search very soon. Keep watching!

[UPDATE: Jan 1 2011] I bought one set on 19s for the road. More here.

Here’s what I found on Tire Rack.

Street (Extreme Performance Summer)

Best: Bridgestone Potenza RE-11 (273$ per tire – 1092$ for all 4 tires)

Or track tires, which are more expensive… I read that the Michelin Pilot Sport Cup are very good, but reviewers on Tire Rack said they are as satisfied with the Potenze RE11. The price difference is 60$ per tire… hum, not sure of which set I’ll be buying.
