Hello, Don't lynch me for asking this, but can I flip each of my rear Michelin diamaris on the same rim so as to maximize tire wear? just concerned if there is a difference between inner and outer side wall strength (as one side of the tire says outside and the other inside)....the direction i a am not concerned about as I can swap the 'new' setup from one side to other so as to maintain direction...any tips by tire experts would be great thanks
