I've a 2006 2.9 CRD and just about to change the front tyres.
I reckon I'm over hard on my tyres by the way I drive, but getting even tyre wear across the tyre (even though Kwikfit staff reckoned the tracking was out a year ago - not going there again - its Blackcircles.com for me now).
One thing I find is that driving in heavy rain or snow, the weight really counts against it and makes cornering in these conditions a novel experience! I have Michelin Pilot's on the front and not using them again as the grip at times is non-existent.
I'm now hunting for a good rain/wet tyre and not worried if they wear more often - I'd rather have the grip. Hope this helps. Once I get new tyres I'll post here and let you know what they're like.
It would be nice if others posted their tyre makes on here with a short dit on their experiences with them. C'mon peeps!
