I've just had Vredestein ULTRAC SESSANTA put all round, also after some good reviews. So far so good, had them about 2 weeks. They grip very well and tyre noise is less.
I bought my 220d 2nd hand and it had identical Michelins on the front, and 1x Bridgstone and 1x Good Year on the rear. So I suppose after that cocktail I should feel a difference!
