On the rear only of a 528i Touring I bought a few months ago. The tires were almost brand new as had beeen fitted after an MOT fail two weeks previously. I have found them to be good in dry conditions and not too noisy. Wet performance not very impressive at all - and show them a slight slope with a grass surface and they will just spin - no traction at all - almost as if they had silicone lubricant on them. The Hankook Ventus's I replaced them with just fly up the same slope with no slipping at all. The Events also lasted a lot shorter time than I would have expected for rear tires (albeit on a RWD car.) 8k miles in - they are down to 3-3.5mm which is about where I would change tires in any event.
Not overly impressed - probably wouldn't buy them.
