Those Pirelli P-Zero Nero M+S ARE THE Tire for Daily Driving.
They ARE Ultra High Performance All-Seasons.
I know you want mileage, and that you aren't Racing.
Don't forget that a Tire that Handles "Great" instead of "OK" is ALSO a Much Safer Tire.
My experience with the P Zero Nero M+S is Amazing.
I hit a large chunk of debris once while traveling down the interstate. Punctured the Left rear with a hole almost big enough for my pinkie finger. Prior to getting it repaired, I had to drive approximately 30 miles on the shoulder and in the slow lane. I averaged between 40 and 45 MPH. No Broken belts or tire disintegration.
I had it patch/plugged, remounted and balanced, (All at a Wal-Mart in a Small town), and the tire gave me another 15+K miles with no problems or vibration.
It's tough to top that.
(Oh, and they Handle Incredibly Well

)
