Gary Howard of the Canadian Automobile Association says a good rule of thumb for when to put on winter tires is when the temperature outside starts to dip below seven degrees. He tells Tide News that's because those types of temperatures tend to bring a risk of frost. However, any earlier and you could risk wearing the tread unevenly.
Howard warns people not to mix and match their tires. He says that's like wearing a sneaker and boot—you will have very inconsistent performance, and it can actually be more dangerous than having all of the same tires.
As for all-weather tires? He says they are okay if you live in a temperate climate like in British Columbia, but not here, where we get a lot of snow.
