Beware of using treadwear, traction and temp ratings on tires...they are a guidline against a particular mfgs 'base' drum tire, and each mfg has their own standard so it is useless to compare a Goodyear treadwear rating against a Bridgestone.
For best comparison, use the performance index (sometimes called a speed rating) because it is a standard applied across brands. S rating means good for sustained speeds of 112, T 118, H 130. V 149, W160 and Y 149+. So for a 180MPH tire, you must find one with a Y service rating to be sure. Generally an H rated tire will last longer than a V rated, but not grip as well. As for wet weather traction, it's trial and error. I personally think the Firestone Firehawk SZ50 EP is the best rain tire I have ever seen (seems like most Corvette owners clubs agree!). I have a set on my Lincoln and my Cobra, and they grip better and last a lot longer than the Eagle F1's I had before.
