At this high mileage, there is likely issue(s) with the suspension that caused this rapid tire wear. As I stated in my earlier post, my e46 M3 had both the front and rear bushings cracked at about 40k miles. They were fairly inexpensive rubber bushings ($60 to $80 part only), but they would destroy those expensive $300 tire in a few thousand miles.
We used the same EVO tires in the G37s coupe (daily commuter) with similar sport suspension as the 370z, it lasted more than 40k miles (f & r), the rear wore out just a bit more on the inside. We just replaced them with the same tires. They are good value tires for DD.
I'd get your suspension checked out with a knowledgeable shop.
