Neat dealership trickery...

cupping tires ARE caused by worn/weak/leaking shocks. the tires aren't
fully being allowed to stay on the ground so as you drive the tires are
bouncing vs. staying put.

If the tires were out of balance you'd notice it as you drive, as your
steering wheel would be pulsing and probably moving back & forth on its own.

Go get a set of Bilstein's.. stay away from stock/OEM.. they're worth the
money.
