In this video wheel-tech gives a classic example of a bent wheel. Do you feel vibration driving your car at highway speeds? It could be that your wheel has a bend in it creating a "hop" that can effect driving. This bend is not always so obvious as the video shows.
Many stability problems are mis diagnosed because the mechanic does not see a bend in the wheel and assumes it is something more involved. This can cost you money! Take the time to visit Wheel-Tech your Rim Repairs professionals before going to an auto shop for a quote.
