I don't know. The fact it is multiple bumps on all four tyres makes me doubt it. However you may be right.

My M2 tyres are extremely noisy, so I went to my local tyre centre to have them checked. I was told there are numerous small bumps on the inside and outside of all my tyres which will be causing the bearing type noise. I have still got the original Continentals on and have done12k miles. The noise started probably around 6k miles. Has anyone else experienced the same problem and what was the outcome.
