McCreary's are not drag radials, they are dirt track tires and are a really soft compound. They did a really good job for me on the Dirtmobile, not quite as good as BFG's but better than Nitto's and they were considerably cheaper too. They do suck hind tit in the rain and wear out rather quickly though. They are no longer called/made by McCreary BTW. They are now American Racer. Once upon a time, you could find a lot of information about pricing and sizes at www.butlertire.com but I haven't been there in a long time. If you can't find anything there, get with Dan at Idlewild Racing. That's where I always bought mine.
