Fitted for 2 years now, and, after recent snow, Have experienced all conditions. For general use, excluding very progressive driving, I cannot fault these tyres. At first fitting, road noise slightly higher than previous summer Conti's until bedded in. Very impressed with comfort and handling on all road surfaces. Water clearance is good, and, with present tread depth, no aquaplaning. Provide high confidence in snow - yes they will break traction, particularly on cornering, but only when pushed. But they give far greater control than summer tyres in snow. On compressed snow/ice their advantages are limited however.
Most impressed with wear rate. At 18k, with relaxed driving style, still have 4mm front, 5mm rear, and have just stopped front to rear. As these have directional tread they cannot be switched to alternate sides (for a diagonal switch).
I have these also fitted to my Ford S-Max (15). Even more impressed with those - though being 225's gives the comfort.
I will certainly be sticking with these and looking forward to the latest upgrade in compound. Having previously been a summer/winter wheel switcher every six months for about five seasons (on my old Galaxy), these really are a great compromise.
