The Mickey Thompson ET Street Radials are much better at the track then the Nittos (stickier and more consistent). The trade off is that the Mickeys are very soft and won't last as long as the Nittos on the street. The Nittos are good in the rain at moderate speeds, however the Mickeys will be ok in rain at low speeds if you aren't driving far. If you will have to drive your car for decent mileage every week and will be caught in the rain often, I wouldn't recommend the Mickeys.
Ideally, you would have longer mileage drag radials such as Nittos or BFGs for everyday driving and a set of Mickeys on a spare set of rims that you could put on in your driveway and drive to the track on. If you don't do much daily driving, the Mickeys are the best. The 16" 255/60 Mickeys are fine at the track.
