I know that we don’t want to talk about it, but winter is coming. And we need to be prepared with winter coats, boots, hats and of course winter tires on our vehicles.
But WHEN should you make the switch?
Generally, tire manufacturers and transport ministries in Canada follow the “7-for-7 rule,” which states that the best time to change to winter tires is when there have been seven consistent days of temperatures below 7 degrees. But the temperature can be hard to predict, especially since we’ve had a really warm fall.
The Weather Network has released a guide showing when cities across the country are expected to hit that winter sweet spot.
Ontario does not have a mandatory winter tire law, but I think most of us do change them over in order to be as safe as possible during our winter commutes.
According to the Weather Network guide, most cities will see that 7-degree consistency by mid-Novermber.
Here are a few specific cities that were analyzed:
- Timmins: October 26
- Thunder Bay: November 1
- Sudbury: November 2
- Ottawa: November 9
- Kingston: November 11
- Toronto: November 15
- Windsor: November 21
