Drag Radials...



DOT Slicks


Slicks




To add to the thread, I've had Nitto Drag Radials (the second example of DRs) on a daily driven car before. It's not too horribly bad in the wet if you're careful. I'd never do it with DOT slicks though. I've also known people to drive 50 miles or so on slicks on the way home, just in case some after track play time was needed. However, they swap back to their street tires after home.
