AWD doesnt means it's a off road car, it just mean the all wheels got power. Being said, AWD will always gives you better traction and safer on rain and snow. Its not only about winter tyres or not in snow, more options in power distribution on different wheels matters too.
I always found the rear of my FWD UX F-sport lost traction very easily even with my new tyres, i think it's the factory suspension configuration. I've driven many cars and UX's rear's dynamic is definitely not on the stable side.
