Ok.. here's what's going on, I got another set of black 18x8 rims i had the car aligned at the dealer after the installation at the rim shop. a couple of days later i was on the highway and around 60-70mph i noticed it started shaking, i mean the steering wheel and u can feel it in the seat too. I was wondering if I may have to balance all the rims, even though the guy at the rims shop said he did.

 

i had a similar problem after getting new tires from just tires.
just tires had balanced them but the toyota dealership had aligned my car a week before that.
the next day after i got my new tires the wobbling started @ around 20MPH or so.
after 2wks of taking it back and forth to just tires and the dealership to see wtf was wrong, just tires told me it needed another alignment i took it back to the dealership one more time and they finally determined that it was due to a bent rim that was put in the front. they simply switched it to the back free of charge and no more wobble

tho since your rims are new i can't imagine that any of them are bent. i would suggest a 2nd opinion, tho. good luck!!

EDIT: it was wobbly AND pulling to the right

 

yea i think maybe one of the weight used to balance the wheel might have fell off, i had that happen to me before
