We either need harder centers or chewier outsides.
Maybe a candy maker could figure it out.
When MM and I were at the Dragon earlier this year and I was getting a new tire, a couple fellows came in for tires and the rear had plenty of tread in the center.......but the sides were gone. He rides the Dragon aggressively and scrubs lots of rubber off the sides. (He and I should rotate tires and he can wear out the sides and I can wear out the center).
They do make sport touring and sport bike tires with a hard center compound and a soft side compound. The sport touring tires are a bit harder than the sport versions. When I use them they don't stay very rounded looking....the center gets a narrow flat spot and the sides wear in wide flat spots with a sharp angle where the soft and hard compounds meet.
MM does a very good job of wearing the back tires out evenly across the tread.....I never seem to be able to do that. The only tire I know of that will fit MM's bike that is a multi compound is the Bridgestone Battlax BT45, and I am not too impressed with it as the front tire has a diamond pattern on the sides and it wears crooked and gets noisy in the turns. The dual compound rear was evident on the one mounted on the Ninja 250 - both of them I had on the Savage Cafe never showed the hard/soft joint and wore the centers out at 6,000 miles.
