If you run the car on the street i'd recommend not switching tires to go to the track and running M/T sportsman Pro tires. They are full tread, drag slick compound with a wrinkle wall design. I run 10's on them with 16-18lbs or air, dead wrinkled hook.
I prefer bias ply for the strip and in many cases on the street as well. IMO the popularity of drag radials is three fold.
1. They produce these in modern tire sizes
2. The next latest great bestest bullshit product you HAVE to have
3. Race classes that require them
If you go drag radial, which I advise against, they like a wide wheel. So if you buy a 12.5" section width tire, it wants a wheel damn close to that.
