MM, Michelin Commander 2 140/90 15 rear and 100/90 19 Pilot Activ front. I'm on my second Commander II on the S-40 . The first one did a little over 22,000 miles before I retired it , it wasn't bald --- just down into the wear bars a little ! Thats easy for me to like. I'm on my Second Commander II on the back of my Sportster too . The first one only went 18,000 + before the wear bars were solid , but its a 200# heavier bike and took all my ridding double chores too.
Most of the time , I ride my bikes like Fun-Bikes should be rode !
Just a little less than the Law will Dis-Allow.
