A bit off topic, but have you (or anyone) using NT-01s ever had tread splice failure? I bought a new set last Fall to run at a Performance Center autox event, and after a total of maybe 12 runs on a 1:30 track, all four of the NT-01s started opening up on the tread splice. Of course two of them on one side were much worse due to rotation direction, but even the two on the other side were showing gaps beginning. I think the build week was 32 (i.e. 3212). Nitto refunded me for the tires and retrieved them to study what happened, but I've not heard back from them.
Even further off topic, I got to this thread after seeing your member name here in this forum and recalling our past discussions on m5board and how you were instrumental in working with Ground Control on the trick front strut design for the E39 -- that work has gone a long way in the E39 M5 community as many have benefited from it. Good job. Speaking of which, I simply can't fathom how long ago that was now.
Lastly, I just added a 2011 E90 M3 to the stable, and I *love* this car. The S65/S62 contrast is interesting, but man the E90 is fun to drive. I'm keeping the M5 (10 years already now), and I may well end up with the E90 M3 very long term too.
I've been, under a recommendation from a local full-on racing shop, running my NT01's at 33~34psi hot.
And, yes, I've had 2 on my set develop cross-slice (shoulder to shoulder) recently. And know of at least couple of other people whose NT01 also developed that slice. In fact, here's the recent discussion --> http://www.m3post.com/forums/showthr...=801222&page=2
