Winter vs All-Season vs All-Weather Tires
Short answer: if you drive out of the city in winter, park outdoors, or do highway distance, buy dedicated winter tires. If you’re a downtown commuter on plowed roads who parks underground, all-weather is a defensible single-set compromise. All-seasons are a three-season tire wearing a misleading name.
The Symbol That Matters
Look for the three-peak mountain snowflake on the sidewall. It means the tire met a defined snow-traction performance requirement in testing. Dedicated winter tires carry it. Good all-weather tires carry it. All-seasons don’t.
What you’ll see on all-seasons instead is M+S — mud and snow. That marking isn’t tested to the same standard; it describes the tread pattern, not measured performance. It’s also the marking that lets a tire be sold as suitable for winter when it isn’t, which is worth knowing before someone tells you your all-seasons are “rated for snow”.
The Three Categories
| Winter | All-weather | All-season | |
|---|---|---|---|
| Mountain snowflake | Yes | Yes | No |
| Grip below −10 °C | Best | Adequate | Poor |
| Ice braking | Best | Fair | Poor |
| Summer wear rate | Very fast | Fast | Slow |
| Sets you need | Two | One | One |
| Insurance discount | Yes | Usually — confirm with your insurer | No |
The Cost Argument People Get Backwards
Two sets sounds like double the money. It isn’t, because each set is only wearing for half the year. Two sets last roughly twice as long as one set would, so the tire cost per kilometre is close to identical. What you genuinely pay extra for is the changeover twice a year and somewhere to keep the spare set.
In Toronto the storage problem is usually the real obstacle, not the money — which is why we charge $99 a season to solve it rather than treating it as an afterthought.
What We’d Recommend
- Condo, downtown, garage parking, short trips — all-weather, one set, done
- Suburban commute, outdoor parking, highway — winter set, no argument
- Cottage, ski hill, anywhere north of the 401 in February — winter, and don’t cheap out on the compound
- Second car that doesn’t move in January — all-season is fine
