ok so i just got some new tires yesterday and after i get done with the money bit of the deal. the assistant manager tells me i've got a wobble in my right reart rim and i might notice some vibration as i rotate them to the front. He said i probably wouldn't even notice it and that it was very mild. does anyone know anything about "wheel wobble" considering i haven't hit anything and i can't feel the vibration at all? Should i consider taking the rims into a place that will true them up or not worrie about it until they actually get bent. oh and they are 5zigen fn01rc rims pretty sure they are strong.
