Looks like a great set of winter wheels you have there, and if the roads are as bad as you say, they will give you a much smoother ride. (that is if your wheels/tyres are 17" like I think)
I bought my 19's with brand new Kuhmo Ecsta KU31's on em. I am gonna change em, just because I have seen an unmissable deal on some Conti's.
All the local tyre guys seem to highly rate the Kuhmo's and TBH I think they are pretty good. Yeah they are quite a bit noisier than my 18" Conti's, and Also, I haven't really thrown the car round many corners with em on, but as a mid range tyre I reckon they are ok.
I think having them as your winter tyres they will be fine
