At first I thought it was my rims, since they are 18s....but lately I've notice that my whole engine is actually vibrating I think...is like is struggling and is about to give up when I reach a certain speed...and sometimes even when I start the car.....anyone else has similar problems and might know what it is??
This really belongs in the problems section. Are you getting a CEL? If you are the code would help narrow things down. I am at a loss to explain it, but two things come to mind right off spark plugs/ignition coils or fuel pump.
is it happening at the same speed every time, if so check your balencing of the tires, if not check a;; your spark plugs you might have a ring or two failing. just a suggestion with out driving it i really cant tell you for sure!!!
