There is no free lunch: If you are getting 12,000 miles or more on a scooter tire you are sacrificing road grip. "Sticky" tires wear out faster then high mileage tires but give you more adhesion, especially in corners. I went down on my Moto Guzzi due to an advertised high mileage tire that spun out on a dry road with no gravel or sand to blame it on, just lousy grip.
Of course, we scooter riders probably aren't dragging our knees in turns, but still....
