Is this rear tire wear normal?

The picture shows the side groove on a rear dunlop q3 tire. The worn part rotates forward. It's on all the side grooves only on the front part of the groove

Thanks for the info just making sure it's not a suspension setting thing

Without seeing the tire in person I'd say too much rebound damping.

Hard to say. Lots of things you can do as a rider to up a tire, even on a perfectly adjusted bike, especially on the street. Take a skilled rider and put him on a well-sorted track bike and you will not see any of the cupping present in your tire. The cupping could be due to a lack of skill, or due to the imprecise and fluid nature of steet riding, or of course due to rebound damping issues. By all means, feel free to adjust the rebound damping. Too much damping (i.e.: too slow) is going to show a raised edge along the leading edge. Too little damping (i.e.: too fast) is going to show on the trailing edge. Wildly under damped suspension will show a totally uneven circumferential wear (not present here).

I wouldn't bother changing anything unless you are an expert rider who wants the absolute maximum performance on the track. But if that were true, you wouldn't be asking us, most likely. What you see here would happen to any bike on the street or any novice to intermediate rider who does not have solid throttle control, even on the track.

Just my $.02. I'm not an expert
