Okay, here's the situation.
I'm driving a Honda CR-Z with 25,000 miles on it, and it's needing new tires. I've run my very first autocross event on these tires two weeks ago, and I can probably run the next event in two weeks, but, well, driving too much more on the street isn't ideal, since my worst tire is at 3/32" of tread. I'm hoping to get a set of four before the end of the year.
Next, I'm driving the CR-Z in HS, and don't really want to dedicate the sort of money required to support having a separate set of tires. I really don't want to change anything about the car, because I'm nowhere near experienced enough to justify changing things. I just want non-crappy tires.
These tires will see rain, and cold days, both around the cones and on the street. They will almost certainly never see ice or snow.
I forsee doing maybe six autocross runs of ~45 seconds each, once a month, so I guess I'm after a performance oriented street tire.
I would sure like to avoid crazy expensive tires, but hey.
I really don't know what else I'd throw out there.
Looking at the Tire Rack, there is a Bridgestone Potenza RE760 Sport. It's pretty reasonable at $88.10 per, and seems to have good reviews. In fact, looking at my Tire Rack purchase history, four will cost about the same as two Eagle GTs for the front of my G35.
