HI, I purchased an immaculate 2004RT about a year ago with 10,600 miles on it. It has Metzler Marathons on it that came on the bike. They were in very good shape but now are in need of replacement. I have only put 4000 miles on the bike. It was like one minute there was tread on the front and the next it was gone. It is also wearing unevenly with the left side being more worn out. I have been told by a BMW friend that this is common with the 1150 RT's. Is this common? If so, is there anything that can be done to prevent this from happening? Looking for suggestions for a good replacement set of tires.

Tom E.
