I knew that they were not going to be great on the highway. Where the problem is was they were FINE on the highway until after the trip now they are not. I am sure it is flat spots. It better be. If I go have them balanced and then the next trip they are this bad again then they are not the tire I want. If I can get them to ride like they did when I first put them on then I love them. I can't believe how bad these flat spots are and how they won't go away. I didn't get a chance to lower the pressure and run them a while to flex the side wall and get it limbered up. Maybe tomarrow. I was hopeing you guys had ways of dealing with this. Z06
