I've had my tires (ZR rated) for about 2500-3000 miles. I haven't rotated them yet. The fronts are down to about 6mm of tread depth. They have 10/32" (7.94mm) when they're new. My alignment and tire pressure is proper.

So does a wear rate of 1.5mm-1.9mm/3000 miles sound about right? Or am I just having way too much fun with my tires??

 

They wear super fast. I got maybe 8,000-10,000 miles out of mine.
