"Cupped" tires???
I got my rims a few weeks ago and they're wrapped in Pirelli P7000's. I assumed they would be a bit louder than my 15's with N itto's but the noise is SUBSTANTIALY gone up. My dad is paranoid so he took it to that tire shop by Super-K...they say my tires are "cupped"...little ice-cream-scoup cups are taken out of the rubber...causing excess noise...ive never heard of this...
How the hell woud ice-cream cup shaped indents be formed in my tires???
He says the back are worse than the front and the back/left is te worst of all
Any input???

Cupped? WTF? Never heard of that!!!
Do you have a camber kit? Remember that those wheels are a size up from your stocks. If you don't get a camber kit, your tires will wear faster. But I have never heard of this "cupped" thing before!
By the way, I always had my tires a few psi under what was stated on the tires. Hopefully you checked the air pressure when you put them on your car, and keep up w/ that. I am sure the pressure in the tires changed over time as they sat in my garage and temperatures changed dramatically.

find a medium between the tire rating and the door rating. the door rating is vased on what the load bearing properties should be. the tire rating is what they're designed to operate at.

OK..here is the best picture i coud take that represents the cup-ness...notice the tire is not round ...looks like a many-sided-figure...what looks like flat is actually indented to form a vague "cup"
