It's difficult to give a rating out of ten for these tires, simply for the reason that they're all weather tires. In most conditions they're great, in some, such as the rare very hot days we can have in the UK, they become OK/good. To be honest, they go off a bit in the really hot weather and wear more quickly that ideal. However, as we typically have cool and moist conditions for the majority of the year, these tires perform well for most of the year.
In the Summer, I can feel them get a touch soft and causes my Subaru to have hints of understeer. This can be fun, but not always. In the cooler Spring and Autumn, they really come into their own. On wet roads the wet-bias allows me to plough through anything and I am more likely to find myself falling out of the seat, rather than the car start to move around in the wrong direction. In winter, because they're not a full winter tire, they lack the total experience, but they're rated M&S and quite frankly, that makes them better than the majority of summer tires.
In short, I have no problems recommending these all-rounders for most people, most of the time, but if you have something with huge performance capabilities, I'd swallow the cost and have a dedicated set for summer and another for winter.
