I bought some used nitto drags off buddy that had them sit on his car without moving for about a year and a half.When took them to the installed he said they were flatspotted.I did notice noise and vibration on the highway with them.I sold them off to another friend who didn't care.Is this a common problem with these.I am thinking of getting a new set as I did like their performance other than the annoying highway noise and vibes.
So are they noisy on the highway? Do they flatspot that easy.Anyone else had same problem of complaints with them?

 

No problems here. I've had them for about 9 months now, and only drive my car on weekends. I don't feel any dofference on noises or vibrations compared to my old GY GSC's.
