Might be worth while considering Michelin CrossClimate. Fantastic in the wet, certified for snow, and good for use in the summer too.
The only problem is that the nearest size is 185/65 R 15 92 load rating V speed rated 68dB €95,50 each.
They would be 6mm lower than 185/70 tyres so that would be something to consider if you had ground clearance issues. The lower car would probably corner a bit better.
