Time for a new tires?
I currently have the new Michelin Premier LTX A/S tires, you start off with lower tread depth, but the tech in these new series are suppose to wear out much longer, and every layer worn will continue to provide the same driving experience.
I have about 12k miles on my set currently, and they have a 60k mile warranty. I like them, and hope they last a great deal, thus far, with normal rotations and balancing the depth hasn't gone down.
