David, if that rotor had perceptible movement then I'd be getting that bearing retightened, repacked or replaced. Especially if you plan on running 450 miles each way. Once the bearing starts to go it won't be long before you are chasing one wheel down the highway while balancing on the other three.
Loose or worn wheel bearings can cause vibration too.
