I don't see it being an issue unless you get stuck. If you are truckin along I don't see getting pulled over. But if you get stuck and start blocking traffic I would expect a citation
Bingo!
In my canyon they require Snow tires on cars all winter long. When you speak with an officer about it Snow tires is the tire that has the snowflake/ mountain symbol on it. Tires that display M/S do not qualify. There is a different compound in the snow tire vs M/S tire.
Cops anit guna pull you over and look at your tires, but if you slide off or get stuck on the road, be ready for a ticket.
