LOTS of tires are M & S-rated, meaning they can function as snow tires. The rating is primarily a measure of what tire companies call the "block to void" ratio. That's how much of a tread pattern is blocks of rubber and how much is the space between the blocks. It has little to do with actual snow performance. Many tires, and all all-season designs, fit the guidelines for and M & S rating.
WRs are an all-season that has a *winter* tire rating, supposedly OK for "severe winter use," or some such thing.
As I understand it, a winter or severe service rating has to do with a rubber compound that stays sufficiently flexible in sub-zero (F) temps, the effectiveness of the tread pattern and the siping on the tread. Regular all-season tires tend to have less aggressive tread patterns, less siping, and a rubber compound that works in a narrower range of temps. This gives them a 40K mile-plus tread life, which is what people want.
The WR G2 are less aggressive than a full on snow tire, but IMHO, it's a difference that doesn't matter to everyone. I've found them to be fine in pretty nasty conditions. Would a true winter tire be better? Sure, especially when it's really bad out there, but most places roads are rarely truly awful for more than a day or so, and bare the rest of the time, so the WR just seems more practical. And if necessary, slowing down slightly is always a good idea. I've never gotten stuck or gone of the road with them. I like being able to run them on the edges of winter --like November and into April-- without thinking about warmer temps and bare roads wearing them down. And they are quieter than snows, too.
