Well, just ordered a new Michelin for the front of my M/T. Really don't have to have it at the moment but will before summer's over. Have 6000 mi. on the original E3 and it seems to be wearing ok (center rib almost gone).Checking around on the web, these must really be catching on, lot of places are on back order...have heard the debate about running the Michelin in reverse rotation or normal, so I called and talked to a rep at Michelin. He confirmed that the wear and performance would be better if it's run reversed. (ONLY on trikes).
