Didn't see anything in archives about this. My dealer told me that the design of ///M rims requires a special machine to mount and demount tires. I'm not exactly thrilled with his price on the michelines and would like to persue other options. He also told me there was some kind of liner in these tires and that the screw stuck in my tread caused a puncture that could not be patched.
The guy had me at a disadvantage as I could relate to the rim design and pseudo RunFlat etc, so I popped the 300 bones for for a right front skin. I feel like I have been taken advantage of, and if so, would like to avoid it in any future tire/rim transactions. regards, Bill
