So I have ended up with a car with 275/35R22 tyres.

The choice of snow chains is limited to:
1) Konig K-summit XXL 67 £390
2) Spikes-Spider SPORT SXXXL £405
3) Spikes-Spider Easy SPORT SPES4 £300
4) Polaire GRIP polyurethane front-fitting snow chains size 150 £260

Does anyone have any experience of these or recommendations?

(We are off to the Alps and will be high enough and isolated enough to require them)

Thanks in anticipation.
