I've also noticed that the small groves on the tyre tread blocks have started to "squish" together- i.e. the tyre has worn down about 1mm since last year but the tread block patterns do not hold their pattern- this might be contributing to the above handling concerns.
All in- this is not remotely a safe tyre to use in even light snow / in-between conditions - which is what an All/season tyre should do. My van is also empty and running standard wheels so no extra weight or other issues which would change the dynamics of handling. Very dissapointed in these tyres and cant reccomend them for anything but summer use- which in that case, you'd be better getting a summer tyre!
