I would run nothing less than a 15 inch wheel and tire. You are ET bracket racing, not comp eliminator racing. There is a reason for the tirese they run and if you look at the numbers, they are not deadly consistent. You should be able to pick up a deal on RJ.
I have not had a hard tail for about 10 years now but liked eithee a Good Year or Hoosier at that time. However, Mickey Thompson is worth a look. Thier tire program for the dragster has come along way. I have been running M/T on my suspended car( 33.5x17x16).
