Another explanation is that the road crowns from the center of the road, to the sides. For drainage purposes, of course. So even driving in a straight line, there is ever so much more contact on the left side of the tread than the right.Just about every MC tire I've ever replaced (thousands) is wore more on left than right...like yours. I read an interesting explanation that because we here in the US ride on the right hand side of the road, the longer distance around left hand corners accounts for tires wearing in this manner. Over the life of the tire this logs more miles on the left tire side. Is it true?...not sure.
