UPDATE: 3/26/11- 30,000 miles later I finally wore my first car tire! I still love it and don't see a reason to go back! I just purchased my second Dunlop SP 5000.
I've had several people asking me about slow speed handling. Here's a video I made showing that it's not a problem.
UPDATE: 7/28/14 - My second Dunlop SP 5000 is gone. Lasted about 26,000 miles. I replaced it with a Bridgestone Turanza 195 55r16 because the Dunlop have almost doubled in price. I've had it on the bike now for 5500 miles and it's performing equally as well.
