I was checking the rear Dunlop E3 tire on my 2008 Honda Goldwing… and I believe that it has some sort of a manufacturing defect. On the face of the tread, there is what appears to be a cut in the rubber, that starts at one edge, disappears in the middle, and then reappears over on the other edge. Dunlop claims that they use a "Multi-Tread" system on these tires, where the rubber compound in the middle, is different than the rubber on the sides. And what makes me think that this isn’t from something that I ran over, there's no damage in the middle, and the cut also follows along the edge of one of the sipes in the tread on the left side. Looks like some sort of a seam to me. I'd like to think that I’m pretty astute about checking my tires, but even I didn’t catch this earlier.
