sup peoples..

i just replaced my back tires with some Falken ziex 502s. 215/45-17....well when i was driving..when i go over kinda big bumps on freeway or turn hard left with minor bumps, i hear a noise coming from the back left...is my back left tire rubbing? i cant seem to find any marks on the tires or where it is rubbing on the fender...

btw..anyone know where to get an alignment for lowered cars in the south bay/peninsula..?!?!
