Michelin CrossClimate tyres have been discussed at some length elsewhere and since the reviews were almost entirely positive I thought I'd give them a go as I needed a new set of boots on the mighty Superb anyway.   Well, I'm about 2k miles into a set of 4 and so far I'm very impressed.   The 1st thing that struck me was that they're very quiet, much quieter than the Bridgestone/Pirelli combo that was on the car when I bought it 20k miles ago.   They grip really well on wet and greasy road
