Why Tire Swaps Matter in Ottawa, Canada
Ottawa winters are unpredictable, with snow often arriving earlier than expected. According to Transport Canada (source), winter tires improve stopping distances by up to 25% compared to all-season or summer tires in temperatures below 7°C. That makes the timing of your tire swap essential for safety.
The Best Month to Swap Tires – Revealed
Experts and government guidelines generally point to October as the best month to swap summer tires for winter tires in Ottawa and surrounding areas.
- Temperatures drop below 7°C in October, the threshold where winter tires outperform summer and all-season tires.
- First snowfalls often arrive late October or early November.
- Insurance discounts in Ontario often require proof of winter tires being installed by November.

Q: Do winter tires wear faster?
A: Not if used only in cold months. Driving them in summer, however, will shorten their life significantly.
