Honestly, the best thing to do is ask what the guys at your local track are running. Chances are there are 1 or 2 tires that most people are using and it is typically for a good reason. Here is a link to AKAracing'stire selection chart. http://www.raceaka.com/tire_chart.php
Almost all tire manufacturer's have something like this and they are usually pretty accurate as long as you know what your track surface is like. Do you plan racing it or just bashing it around?
