I look back here on this site and see people experience tire cupping issues almost from day one with seemingly no reason. Maybe we now have one, I dunno. Time will tell I guess.
I think you/we are onto something here. I've seen posts attributing RF tire cupping to wheel bearings, etc., but those stock wheels are so thin at the edge, how could it NOT bend the wheel to hit a curb? I had the same observation, TiredRetired, that there's no real vibration at highway speeds, but maybe the tire is absorbing it and wearing accordingly. Dunno. I'll have mine checked. I had new fronts put on three years ago and I believe they spin-balanced then, but now I'm wondering.
