Well I should be getting some slicks here in a few weeks and I want to understand the science behind selecting the right ones.

The question pertains to selecting the right size and width so that you have just the right tire to not lose MPH in the track and not have to small (in diameter) of a slick.

Also whats better and why for someone with my setup:

Drag Radial
ET Streets
Slicks

I just want to buy the right tire for my setup and knowing that its going to help me and not hurt me. I have some stock 16'' wheels that I can mount them to if that helps with anything.

Thanks,
david
