Since I can post pics now, I can show you my Florida chicken strips. I think they look to be around 1.5 to 2 inches? Then you can see the center is where 90% of the riding is done. These are relatively new Dunlop Road Smarts. So far they have been awesome! I'm comparing them to the Dunlop Qualifiers that came stock on the bike. So far, they are doing great.
