All the 3PMSF symbol means is it passes the tests required to earn that rating. Cooper calls the AT3 4S an all season tire... if it was a winter tire they’d sell it as such.Mountain Snowflake emblem.View attachment 33979 Call it what you will.
But you could buy much more effective winter tires if you're going to run separate winter tires.One more thing about running 3PMSF ( Moutain Snowflake) tires only in the winter. I know it’s a personal decision whether you want to have a 2nd set of tires around, but the functionality of “winter tires” depends highly on thread depth. If you are are wearing them out in the summer, they will be that much less functional every subsequent winter. If it’s a storage or convenience issue than so be it, but otherwise, I take them off in the spring and don’t put needless wear on them in the summer.
Well, no.Once you have a Mountain Snowflake designation, the rest is window dressing and marketing. However, to check this out purchase a durometer and check to hardness of the rubber at temps below 7 degrees C. (45 F)
