yes it is being replaced. I was looking for other sizes and they were also on closeout at Tirerack. Hopefully Dunlop will make a replacement as the tire has been around for a bit already.
I don't know if the hancook rs4 or kumho v730 is made in our sizes, but those are the longer lasting and less likely to overheat tires I'm looking at instead. v730 are so cheap too.
