1. Take the time to have your suspension set up by a professional. It's kind of expensive, but worth every dollar.
2. Check your tire pressures before rides. 90 degree valve stems and a good gauge make it easy to check tire pressures, which makes me more likely to actually check them.
3. <from here on out these are my opinions>
I've put 16,000 miles on my 1200s. I'm a heavy set rider and I'm consistently hard on the throttle. I've killed 1 set of Rosso II's, 2 sets of Rosso III's and 1 set of Angela GT's as well as 1 or 2 Rosso III back tires. By far the Rosso III's where the most rewarding. They held their lines, even when I made mistakes, and handled the corrections well. I switch to Angel GT's only because I was going through Rosso III's quickly. That's almost entirely because I'm heavy set and not a result of poor manufacturing. As a result of proper suspension setup, management of tire pressures and the confidence gained by top quality tires I worn the Rosso III's out on the sides before the center patch.
The Rosso III's strike a really good balance between price, tread life, confidence, feedback, dry handling, and wet handling. There is a big difference between the Rosso III's and the II's. I highly recommend buying them from DennisKirk.com they tend to beat everyones prices on Pirelli tires by about $15.
Additionally I plan on tossing on a pair of Diablo Rosso Corsa on this year for the start of summer knowing full well that I will be swapping them out halfway through the season.
