Your thread title might be better: All-Weather Tires vs All-Season. All-Season tires are more properly called 3-season tires. They perform poorly in snow and ice. All-weather tires are true year-round tires. All-season tires are biased toward summer weather where all-weather tires are biased toward snow and ice performance. They have the 3-Peak Mountain Snowflake designation that good snow tires have but they also have a tread life warranty. I put on Toyo Celsius all-weather tires and my car (an Acura RSX at the time) was an absolute tank in the snow and ice. This was in Idaho. I ran the same tires 3 winters in a row and all year round and they performed just as good the third winter as the first. Incredible tires! They gave me such confidence in the winters.
On the down side, the Toyo Celsius tires were expensive. They were a bit harsher riding than the Michelin Primacy tires I had been running. My impression was that the Michelins got slightly better fuel economy but that's hard to measure. The difference was slight. Overall, I'd buy the Toyo Celsius tires again if I still lived in that area.
