I have a Michelin PR2 on the front of my ST1300 (3200 miles) that has a jagged cut that I just noticed today. It is about 1 inch long, 3/8" deep, and in the center of the tread. I do not recall running over any sharp objects and the tire loses no air and runs as smooth as ever. The gap / opening of the "smile" is about half of the diameter of a pencil lead. Obviously I have some concern about this and was wanting any comments from others. I hate to junk a tire needlessly.
I haven't had any luck yet getting a picture attached.
