Michelin Cross Climate are a very good Summer Biased All-Season - Very quiet too. Fitted to my FWD work whip. Very good wet weather performance and capable in the snow. Seem to be lasting longer than I imagined too.
For the CS, I have two sets of wheels...
Summer wheels - Michelin Pilot Sport 3
Winter wheels - Continental Winter Contact TS860
I can't recommend the PS's and Conti's enough Both exceptional when in their element, but the PS's are utter rubbish in deep Winter - even on a 4WD with LSD.
As good as the Cross Climate's are, they are still a comprimise in the Summer when top performance is demanded. But probably the best all-season out there if that's what you are looking for.
Have a smooch about on tyre reviews. Sad to spend time looking at tyres I know, but being so expensive it's nice to have all the info to decide what's best for you
