My Michelins are slightly noisier than the Pirelli P7s I had as stock on my Ecomotive, but quite a lot quieter than the Pzero Rossos I had on the FR. I find the Leon generally is pretty noisy for tyre/road noise - one of the noticeable differences between it and the posher VAG siblings. Doesn't bother me terribly though. I do notice the Michelins make a drone/whine noise if driving through prolonged stretches of standing water.
They're great on frosty mornings like today though.
