I can't answer this question, but I've driven a few Customer's cars with the 555s on them and they were pretty nice, but when do you get to drive your car to the limit of the tire on the street?

If you are only going to have one set of tires, then the 555 is a nice choice. Wander over to Yellowbullet.com/forum and ask the question in the drag race section. More radial guys over there than here.
