Pretty common wear pattern. Do you feel more comfortable in left turns than to the right? I do and tend to take them more aggressively.

If you feel more comfortable turning one way over the other I recommend to you what I did. I cannot even remember which side I favored now, but when I realized I didnt feel comfortable leaning into a turn (left or right) I made sure I made that turn OVER AND OVER until I felt as comfortable as the strong side.
Now I can scrape either peg just as comfortable and I dont even think about it. Its not good to have a side you dont trust
