thanx guys... yeah Andy, in my case it's only rubbing from the back.. I dont know if its rubbing metal from the inside or the outside, like u said, "It's hard to diagnose by myself" unless I put 5 or more people in my car (specially in the back seats) and check for myself if there's any possibility that it's rubbing from the outside, and if not, then its rubbing from the inside or with the suspension.... and I need an alignment for sure, so there's no really easy way of doing something to stop that rubbing?? ( just gettin smaller tires or rims... hehhe) and I wanted to clear something out, the steering wheel only shakes at 55+ mph....

and can someone clear something out for me??

205/40x17 tires >>>>what does the 205 and the 40 mean?? I know 17 is the wheel size..

and my wheels are 17x7.5 I think >>> what does the 7.5 mean??... is it the width of the wheel???
