Take your car to reputable shop have them take the tires of the wheels and mount just the wheel on the balancer and spin it you'll be able to see if it is bent or not.Maximium run out should be no more than 0.030 thousnads of an inch if it's bent more than that have them trued if not replace the faulty tire or tires Michelin has a really good waranty if you don't have a lot of miles on them.Hope this helps.
