Rotating them will DEFINITELY correct the cupping.
Also, running too much PSI will absolutely cause cupping, as will worn-out shocks.
However...it IS reversible, especially on these tires. They will correct themselves quickly.
Don't let the tire shop rip you off by telling you it isn't correctable.
I've fixed cupping on these exact tires that was caused by my error (not rotating them frequently enough and running them too hard on my TOAD for less rolling resistance). After about 1000 miles, the cupping was gone.
