Dunlop Elite 3 cupping??
Dunlop Elite 3 cupping??
I have one of these on the back of my '07 Ultra. It has maybe 10,000 miles on it and is cupping pretty bad as the tread rolls out from center. There is almost 1/8" difference in the rubber from the front of any given groove to the back of the it. Has anyone else had this happen? Running 40 psi always.
I can feel some vibrations at highway speeds and its starting to roar/whine a good bit in turns. I have the IDS and SE compensator so none of it can be blamed on a lack of either of those.

Also with 9,000 miles on mine and noticing the cupping described here on this thread. Also, by touch (not with a thermocouple) the outside of the tread feels hotter than the inside. I'll have to take my tire pyrometer with me today and get some really accurate readings. When I was racing we would measure a tire in three locations; Both outside edges and in the center. The ideal readings were to get the same temperatures across the entire face of the tire. We would use these readings to fine tune our tire pressures and alignment.

Yep. On my 3rd E3 rear and every one of them has cupped, regardless of pressures. I get about 8k out of the rears, and they start cupping around half way.
