new shoes
So the factory full summer tires were at 23k and the days are starting in the upper 30s and running to the low 60s. On rain a few cold days these things were alarming, so I went back to Michelins (I've run them on my last three sedans and my pickup with good results). Gran Turismo East took care of me, been doing business with them for a while.
They said something interesting:
The rear tires are factory at a -2degree camber. They said it was to help prevent spinout, but at the cost of uneven/premature wear and that there is a kit that will put in a different adjusting cam and provide a greater degree of range so the rears can run flatter (larger contact patch). The 370z is also my first car where you don't rotate tires, which I can't imagine won't lead to a shorter lifespan as well. They also said that as the springs fatigue, the degree of camber increases and that the left rear on my car was at -2.3, out of factory spec of -2.2 to -1.2.
I think I'm going to put some miles on these (considering spending turkey day running the dragon's tail) and see how they wear in/if this is an issue. If it does, it may be on the list for round 2 along with the differential.
