I suffered with this from the day I bought my car at 11 months old and 5k miles until about 6 months ago. It was subtle but annoying and drove me mad - sometimes the dealer agreed it was there, sometimes they didn't.

Had all 4 wheels road force balanced - didnt help. Replaced rear tyres - didn't help. Replaced front tyres - helped a bit. Had them all road force balanced again. Suddenly, it was almost fine. Replaced rear tyres - now perfect.

I still don't really know what has fixed it, but it's like driving a different car.

I think the problem all a long was a combination of tyres and people who can't balance wheels properly.
