The treadwear rating is somewhat misleading. Across different manufacturers it is a more or less useless number. The treadwear rating also really only applies to tires you can rotate fore and aft -- which we cannot with the Z with sport or touring packages. The Michelins are warrantied for 30,000 miles, unless you cannot rotate due to staggered setup, in which case the warranty is 15,000 miles.
Anyway, I was down to treadbars on the Potenzas at 16,000 miles (on the rears) and my fronts still had about 5/32" tread. I actually sold my frons to a G-35 guy for 140 bucks.
