Strange problem with new Hankooks...

Just replaced the DWS tires (which replaced the Bridgestone runflats) on my 335is with these top-rated Hankook Ventus S2 noble 1 tires. At low speeds only, like 20 or 30mph, the car feels like it's bouncing along the typical lousy roads here in NJ. On perfectly smooth surfaces it's smooth. And at high speeds there's no problem. But at low speeds it's as if the tires and the suspension don't like each other. Had tires road- force balanced. Never experienced this sensation before on any of my 7 previous BMWs, or on my previous 335i. Any ideas?

Double check the tire pressure. They may be inflated too much.

Thanks, but I tried that. Already down to 32 front 35 rear. How low can I go?

by that I mean that the car feels jumpy, like it's bouncing far more than it should for the road conditions and speed. Actually, it feels pretty much like an out-of-round tire feels, but the faster you go the smoother the ride. And that's not how an out-of-round tire should act. Right?
