Every fall the same thing happens in Edmonton. The first real snowfall lands, the roads turn to glass on the way to work, and half the city phones a tire shop on the same morning. The people who switched a week earlier are already home.
The short answer: at 7°C
Swap to winter tires once daytime temperatures are sitting at 7°C or below. That is roughly where the rubber in an all-season or summer tire starts to stiffen and lose grip, snow or no snow. A winter tire's compound stays soft well below that, and its tread is cut with thousands of small slits (sipes) that bite into packed snow and slush.
In Edmonton that usually means mid-October. Don't wait for the snow — by the time it arrives, the waiting lists have too.
When to take them off
The same rule in reverse. Once daytime temperatures are staying above 7°C in spring — usually April here, though May snow is not unheard of — winter tires start wearing quickly on warm, dry pavement. Swap back and they will last more seasons.
Do you need winter tires in Alberta?
There is no law in Alberta that requires winter tires on your own vehicle. Quebec requires them, and British Columbia requires winter-rated tires on many highways from October to March — worth knowing if you drive to the mountains or the coast.
But "not required" is not the same as "not needed." An Edmonton winter means weeks below −20°C, freeze-thaw ice at every intersection and packed snow on residential streets that the plough reaches last. At those temperatures an all-season tire is hard rubber. Some insurers in Alberta also offer a discount for winter tires — ask yours.
Which winter tire?
Look for the three-peak mountain snowflake symbol on the sidewall. It means the tire passed a standard snow-traction test; the older "M+S" (mud and snow) marking does not. All five Haida winter lines we stock carry the three-peak mark, and the HD657 is the studded option for the worst of it.
If you really don't want to swap twice a year, an all-weather tire is the middle ground — see all-weather vs winter tires.
