Am I bein scammed?

Well guys, I got Michelin Super sports tires on the rear end. I've been driving with them on since sunday and something feels a little fishy. The guys at the shop balanced and aligned the car but something feels weird. The alignment feels okay but i feel like as I increase speed the car begins to almost wobble or weave a little bit. I'm not sure if this is because the wheels are not properly balanced or the rear tires are new or its because I have different rear tires from the front tires. If anyone could give me some help that would be great, thanks.
