Read the sidewall
Transport Canada recommends looking for this symbol when shopping for winter tires. It indicates a defined severe-snow traction performance, but two marked tires can still behave differently on ice, slush or dry pavement. Check the exact tire's age, condition and suitability for your vehicle.
Do not confuse labels with conditions
A marking does not replace safe speeds or sufficient tread. B.C. has its own rules for accepted tire markings on designated highways; Québec's winter-tire requirement should also be checked with provincial guidance. Ask a qualified tire professional if you are unsure whether your set qualifies.
A sidewall check at purchase
When a seller describes a tire as “all-weather,” look at the actual sidewall marking and ask whether it meets the rules where you drive. Then inspect tread and condition. The symbol is useful evidence of a standard, not a guarantee that a worn tire will stop well on ice.
