I drove yesterday and today, no problem even though snow was about 10" deep, I drive a rear wheel drive bmw 3 series compact, all tyres are low on tread and I haven't got stuck, my mate wasn't so lucky in his M5 though, he covered quarter of a mile got stuck diagonally across the road with one of the rear wheels in the gutter, he called me at work to come and push him out. 
Let me get this right....you drove through 10inches of snow in a 3series beemer with worn tyres? 
Yes the car was actually scraping the top off the snow, it was all fresh so compacted down under the tyres, out of town it was only about 5 inch deep but in town off the main road where no one was driving on it, it was a lot deeper, a lot of snow blowing along and getting stopped by parked cars and building up, I had to dig myself into my house when I got home at 02:00 in the morning as it had blow half way up the door. Got my mates M5 to his yard and when he opened the door it pushed snow out the way it was so deep. I did get stuck there today when I took him to work as my car just couldn't push through the snow built up in front of it, his lorry didn't have the same problem.
10 inches or 10mm? You're talking to us now, not your wife. 
For all the winter tyre sceptics, it's not all about the snow. Winter tyres are much, much better than normal tyres at lower temperatures even on dry roads. I needed 4 new tyres in November, so thought I'd give a set a go. The difference on cold, leafy, slimey, wet roads is so noticable. Having been driving for 24 years and "managed" without feeling the need for winters for all that time, I really wish I'd fitted them years ago. The extra cost is also negligable, as you can only wear out one set of tyres at a time.
I don't have a wife but I do have a girlfriend, I presume you are talking about me telling her my c0ck is bigger than it really is? If that is what you mean I tell her I have a 6 inch c0ck, but I'm talking about the width when looking down at it.
If it makes you happy we'll say the snow was 1 inch deep and I got stuck constantly and then crashed.
