Brother has these on his Suzuki Grand Vitara and is happy with noise level, but has not been through a winter with any appreciable snow yet. He got them because his car has the pressure sensors in each wheel, originally got Nokian WR D4 on steel rims but had such a faff trying to get system to accept other sensors that he gave steel wheels and tyres to his son ( who has a Vitara as well, but does not mind the continual warning light ) and got the Cross Climates - his car has 4 wheel drive so they will probably be OK, even if not as good as dedicated winter tyres. We have steel wheels and Nokian WR D3 on our cars, I wax and polish the alloys with summer tyres on up before storing them over winter and they come out in spring all shiny and new, if steel wheels looking a bit the worse for wear after winter they get a wash an a touch up with Hammerite. Alloys take a pasting in winter, the salt really eats into anywhere it can get..
Tyre compounds have really improved in last 10 years and our winter Nokians ( after 4 winters October to March each year ) are still showing loads of tread. The Nokians are actually quieter than the Michelin ES+ I had for summers before switching to Avon ZV7 on Civic and Avon ZT5 on Jazz ( 15" on Jazz ) and give a smooth ride.
