So just to get the obvious key element out of the way....... I don't think you can get winter tyres for the 22" wheels nor chains. So, since it's the rubber boots that make the most difference in the snow, either specify 20" maximum rims or ensure you secure a set of winter rims in addition to your 22" car.
As for the AWD system, I am convinced it will be fine. It's very sophisticated, has the ADSR function for low speed grip in adverse conditions and plenty of ground clearance to prevent the snow plough effect in deep snow.
I just love it when the deep snow arrives, the car is wearing new winter tyres (they lose their magic at 4mm depth) and with AWD it's almost invincible. That's when everyone drools over your AWD SUV and the stampede begins to buy 4x4 and winter tyres. If you could time a private sale in such circumstances then your residuals would go through the roof!
