I didn't change tires.. I bought the car in feb, previous owner changed rear tires.. I aligned them at les shwab's.
I'm not sure how it was before.. I myself didn't notice the noise until recently... but then again I thought that crazy vibration at 3k rpm, extremely hard shifting and paying 1000$ for "brake job" to dealer is normal...
It's my first used car.. and I'm freaking out from time to time
Thanks for all the good advice!
