Most Provinces (states) up here are not allowed which are the Eastern Ones that Have Salt the Roads all winter and it clears away the Ice except for on the rare occasion it gets below -20. Here in Alberta (Or West of Kenora in "No Rust / Original Exhaust Forever Country") don't think its a problem to have for year round and I haven't seen a stud Claw mark in the pavement for years like back in the 70's when they were needed. But Yeah reason I don't got them is I am fine 98% of the Time, But Good Point, Don, have seen studs let go and take out Windshields too.!
OP, Didn't mean to thread Jack but I recommend either 2 sets of Tires or a Good Snowflake year round Quiet Tire like the Duratrac.
