nitto nt555 extreme zr is the type of tire. I purchased these for my z28, but didn't like the look of them. They have less than 5 miles on them, only mounted on my wheels, drove the car from my tires shop to my house, absolutely hated the look of them and now my car has stockers on the back for now. paid at least 500 for the set, asking 315 for both. My loss, your gain
