i had similar issue,
thrust arm bushing, bent wheel, unbalancing tires could be the reasons.
I had bent wheels, worn out thrust arm bushing.
they both covered by dealership tho. Funny thing is my indy mechanic found out worn out thrust bushing when dealership told me they couldn't relocate worn out bushing, but I told them drive the car and they finally agreed to change the bushing.

sorry for the delay, the bushings only, it will be ok!!

I have a thread on basically the same issue. Got new Hankook Ventus V12 tires and now they're making my steering wheel shimmy. Took it to the dealer and they claim everything is balanced and that it is the "Non-OEM tires" causing the issue, which is bogus. I may have my indy mechanic take a look at the control arms. I got 77k miles on the clock
