Agreed, when wet they are a little edgey, not too bad though but there's less rubber contact with the road compared to a summer tyre as the drain channels are so much wider.
In the snow however they come into their own. After driving to a garage on RE050's and coming out on some winter tyres (forgot the brand) the difference was night and day.
they're useable in the summer, but not advisable as they degrade very very quickly. I went on the Pistonheads fish and chip cruise with them on, but car squirmed in corners taken at speed as the tread blocks on the tyres moved around too much.
And as said before, winters are for average temps of 7c or below, its too warm still for them most of the time, mine are going on in about 2 weeks time if the temperature drop continues however.
