Yes, just a bit. I haven't heard from anyone else getting this cupping of their front tires on stock truck, so I'm still expecting to find some part of the front suspension at fault on my Montero. I have heard from other Yokohama tire owners with different vehicles that their Yoko's tend to cup wear as well. Maybe it's a Yoko thing and not my truck's fault.
