Recommended tires with a 200 or more tread rating for the Optima Face-Off?

[mike343sharpstk]

Anyone have any recommendations on a good, affordable, sticky 17” tire with a tread rating of more than 200??

I was filling out the paperwork to enter the 2012 Optima Ultimate Street Car FaceOff at Road America and I got to the part where I had to fill in information about my tires, here is where the complication comes in...

The rule at the Optima events is that the tread-wear rating has to be more than 200. Turns out the Cheep Sumitomo HTR-Z tires I bought have a tread-wear ratting of 160.
This was a surprise as the tires are not especially great. I don’t think I can afford 4 new sticky tires by June 22, but in the event I can I’ll do some research now.

I was hoping to see how a garage-built Rambler would stack up against the competition. Plus this just seems like on hell of a cool event to participate in.
