I have the Nitto 555R 305/40/18s on a 10 inch rim. They work very well for me. I get great traction on the street. I was blowing my regular 285/40 Nitto 555s away all the way into third gear before switching to these. They also ride better. I guess that is due to a slightly taller and softer sidewall. Unless you are a diehard drag racer running a lot at the strip, these will work great and give you some mileage. If you want a drag radial for ultimate traction at the strip, then jump to the 505R or the MT ET Street, but be warned they are not going to last nearly as long as the 555R.
