Mine wore the OEM Conti's enough in 20K that I'm saving them for re-install when the lease is up. Running Toyo "Avid" TRZ's on there now, AND rotating them every oil change. The TRZ's were as highly rated as I could find. So far (about 8K on 'em) so good.
Dunno if that premature tire wear is an AWD deal or what. My niece's Montana AWD mini-van ate its OEM Conti's in 12K (!!!!) miles and the dealer blamed it on not rotating the tires

, so, I figure I'll rotate the heck out of 'em.
