Experiences with Toyo M144 tires in winter

I didn't have Toyo's but ran Goodyear Steering tread tires on my drives and made the trek from central Alberta several times with no incident. I got caught in a snowstorm around Jasper once and drove through six inches of snow with no issues. A really steep hill would probably been different.
I did buy a set of cable chains but never needed to put them on. Cheap insurance to have them along.
I always watched the weather forecasts before travelling and stayed off the road if a storm was coming through.
