That cupping is definitely the cause of your interior noise. Aside from the camber, severe cupping can also occur if your toe is off. It's best to get an alignment just to true things up. At this point, the only way to get rid of the excess noise would be a new set of tires. What were you using before these Toyos? Did you ever seen these excess cupping on the inner edges? My last set of Bridgestone Turanza did start to do the same thing in the last 10K - 15K and I did find the toe to be off a bit when I had an alignment after putting on my new Pirellis.
