Slight shaking in steering wheel

[kosteniuks17]

I just recently put on some new tires, Kumho, got all four balanced and a 4 wheel alignment this past weekend. Now when im on the highway, usually between 75-82 mph the wheel will have just a very subtle slight shaking in the wheel. It kind of pisses me off cause I had the cheapest tires on the p5 earlier, Nexen, and they had no shaking to them. Anyways my questions is, what do you think is causing the wheel to shake? You the think they werent balanced right? I mean the guy that did my alignment seemed pretty straight. Thanks for any help, I just am very nit picky with small things haha. Do the tires just need to get broken in?

Weights may have come off causing unbalance. I have a bent rim that causes mine. Not sure if they were able to get a good balance or not but at some point in rotation it will become unbalanced. Perhaps that's the case as well.

Or the lugnuts aren't tight...doubtful but I've seen it happen

Okay so I got back from the tire shop, and supposedly the dumb a&% didnt balance my tires at all. Oh and the guy pointed out that one of my wheels are bent and showed me it circulating on the balance machine and its definitely bent. The vibration is almost not there now but im thinking i might switch out my rim sometime. Does anyone on here have a 2003 steel alloy p5 rim? Not the plastic 2002 rim.... Pic if possible and how much? Thanks
