I used to run on Nitto DR's. They were great for the street. I didn't own them long enough to get an idea of how long they last but the traction was so much better than street tires.

The NT05 is suppose to be great too and IMO is a better tire if you aren't going to the track. The 555R will have a soft sidewall which is great for the track but annoying IMO on the street in corners.

 

my first set laster about a year and im on my second now, i love them and have nothing bad to say about them

 

i have the 555 streets..they were nice on my 17s..not much for grip. then i went to the 15s with bfgs and ive gotten about 3k miles on them and they are gone already.
