Tire recommendations

[GTOger]

The wife and I are planning a road trip (Dallas -> Las Vegas -> Dallas) in the spring. We're prepping the ZR-1 for the trip. One area I'd like to think about are the tires and wonder about recommendations from the group here. Here are my considerations:

• The GSC's on the car are older. They don't show any signs of rot, but I've been down the old tire blowout road before, and I'm not anxious to do it again. I'll be most comfortable with new shoes.
• Our Z will spend most of its time on the road. Maybe once or twice a year to a track event. So priority is overall comfort over max performance. These GSC's seem awfully noisy and if there's something quieter out there, it's worth a look.
• Money is an object.

I understand the Goodyear Eagle F1's are pretty popular, and Kumho seems to make a good ZR-1 tire.

Tire Rack is selling something called the Sumitomo HTR Z for $490/set (as in, all 4 tires). Being that's less than what I paid for new meats on my pickup truck, I'm both interested and skeptical, but it's almost worth it just as a test.

Thoughts and input welcome.
