I live in San Diego County in SoCal, but work in the far east county area, so have a commute that takes me from SD metro area to rural work location on a paved county road @ 3100 elevation. I get there via freeway to county road. This tire came as OEM with vehicle & I expect I will get 35,000 out of them before they have to be replaced (with the same tire). County road I drive on is winding & old asphalt (course, but not rough or broken), so these tires have gotten a workout. Seem to still be as quiet now as when I first got vehicle new. I get about 30 MPH average fuel economy on a car that has a 300 HP six-cyl engine with twin-turbos. I attribute a good portion of that to these tires (better than US EPA specs for fuel economy on this model). Car has been from West Coast to DC via Atlanta & back via Fla Gulf Coast - no problems at all in any conditions encountered. Went conservative on snow performance since I've only had limited experience with that (we do get some snow where I work in SD - I know, we're not supposed to get snow in San Diego). Wet & dry performance are exceptional. They have held grip in circumstance when I would have expected they would let go (hard braking). Can't say enough about this tire.
