the unfortunate thing about being forced(here in Quebec) is that people who dont have the money to spare, are buying used winter tires.The cheaper the tire, the less tread it has.Tle law here says 4 winter tires, it doesnt say they have to be GOOD winter tires.
Most car dealers are now giving 'FREE' winter tires when you buy a new vehicule.Of course we know that the cost is hidden in the price.
