I am using a Hoosier 30 x 9 radial slick and I really like them. I would definetly use tubes if you go with M/T. I have a set of M/T slicks and they wont hold air at all. I mean they go flat in about 30 minutes. My Hoosier hold air as good as a tire with tubes. They held the same pressure all winter without tubes. I do a good burnout and they will hook good for me but of course its only a mid 11 car and most of my racing is T & T or Mopar events as I am not an every weekend racer. I can also tell you I have been driving on the street with the Hoosier radial slicks since April of 2009 and they handle great ! I have raced on them 3 times and put over 2000 street miles on them and they still have plenty of tread on them. I just have to be careful if I get caught in rain. Ron
