Avons here. The original Metzler MEZ4s lasted 3700 miles; the rear was toast when I replaced front and rear with Avons. Great tire, love the grip dry or wet. I was expecting excellent mileage, like 8000 or so, but it's not gonna happen. I'm at 3300 on the Avons, and I'm just about down to the wear markers on the rear. Front looks good enough to maybe squeeze another rear tire with it, but I'm not going to bother. I've got new meats waiting in the garage, so I'll push this rear a little more, maybe to 4000, and then change both.
I swear it's related to these hot Texas roads and to the composition of the road surface here. They are really rough, the new road surfaces. I mean abrasive, very abrasive. Great traction, but hell on tires.
I've bitched and moaned about this before, but it doesn't bother me enough to make me move. I can't think of any place I'd rather live.
