I was driving home today and my car has developed a shake. I checked air pressure and lugs both were good but noticed that when I bought the wheels one of the tire is mounted backwards (it has been raining since I got them so I have had no time to really look at them) it is not a rotor wobble b/c it stops when you hit the brakes. I haven't come near a curb or pot hole and I am stumped any ideas? could the one tire be making it shake it is really only at slow speeds.
