I just got the Hankook V12's installed this morning in the 275/35/19 and 305/30/19 sizes. They look awesome I wasn't sure about the wider tire I thought it might be too wide for the stock sport rays. I was wrong there is a small bulge but its not bad at all. The tires grip very well (straights and corners) and I am coming from the NT05 so that’s saying a lot. But I do feel my Z over steers a bit more but its not that bad. I don’t think it’s the tires lack of grib but the back tire is slightly shorter then the front 26.3 R 26.6 F. It would make since because the Nismo Z owners say they have a bit more under steer from the larger diameter rear tire (26.9) to front tire (26.7). Over all I am very pleased with this tire setup, enjoy the pics!
