NT05 treadwear is 200 and the 555 is 300.

 

You got it. And if people are honestly worried about the tread depth, these tires have a higher wear rating than the nitto d/r's and more tread depth and people are getting 15,000 miles out of these drag radials. So they will last longer than the d/r's, handle better than the d/r's, take rain better than the d/r's, and from what ive heard they hook pretty well on 03 cobras so thats where my vote goes.
