The brand of tires that I hear most people liking are the MT's. While in Tucson I raced my 64 just to see what it would do on street tires. I asked quite a few guys about slicks.
Again, most including my brother run the MT's but there were those who loved the Hoosiers. A couple of guys recommended street radials. I am looking for some MT's to buy this year and run my car again with the slicks. Not sure this helped. Larry
