but i just dont think its the tires, i rotated them and the vibration is still the same.. the reason i dont think its an alignment issue, is it never did this before. as soon as i took it up to 75-80 mph for interstate 20 miles the vibration was there after that...so i thought a busted belt in a tire, but all tires look fine and vibration is the same after rotation..and a cv joint going bad wouldn't vibrate in neutral right??
