2 Bent Rims, sonuva... Options

[SimmaDownNow]

So anyway, I finally found out today that the reason that my steering wheel (and subsequently, my car) vibrates between 60mph and 90mph is because I have two bent rims, both on the driver side (the front one is much worse than the rear). So the guy was going to rotate the front bent rim to the rear passenger side, but I have directional tires (Potenza RE750s), so instead he just switched the two bent ones so that the majority of the vibration will be in the rear of the car. Now my dog gets the rougher ride since he's the only one who rides back there. Anyway, is there anything I can do (or have done) to straighten them out? I really don't want to buy 2 new rims, but it looks like that's what I'm gonna have to do. Sonuva...
