To me, with the Z it's all about handling, not how many miles the tires deliver.

Used to be that all tires were around 11/32 each tread depth, don't know about these type of tires.

I do have to say that for OE tires, these Bridgestone's do a really great job on the road. Can't really say anything bad about them. In fact, I really like them. Very pleased with them. Seems like I should move up for my next set, and I most likely will, but I don't know, these have been great tires so far.
