There’s been a lot of tire talk lately, which is great. Winter is coming, and you obviously want to be prepared.
We want you to be prepared, too. So, we thought we’d go over the four types of tires you are permitted to use when driving high mountain passes and other signed BC highways requiring winter tires for passenger vehicles.
1. Studded Winter Tires
How to identify? 3-peaked mountain and snowflake symbol on sidewall and metal studs on tread
Perform best in? Wet, rough ice, and heavy snow; temperatures below 7C
What else should you know? Studded tires with studs up to 2 mm are allowed on BC highways from October 1 to April 30. Vehicles weighing less than 4,600 kg can have up to 130 studs per tire, and vehicles weighing more can have up to 175 studs per tire.
It’s also important to note that you should use studded tires on all four wheels for optimal control. Legally, you cannot have studded tires only on the front wheels.
2. Non-Studded Winter Tires
How to identify? 3-peaked mountain and snowflake on sidewall
Perform best in? Rough ice and soft to hard-packed snow; temperatures below 7C
What else should you know? Full winter tires with the mountain/snowflake emblem maintain good traction in winter conditions because they are composed of a rubber compound that stays soft in cold temperatures. They also have an aggressive tread design for added traction on snow and ice.
3. All-Weather Tires
How to identify? 3-peaked mountain and snowflake on sidewall (ask tire dealer about the differences between winter and all-weather tires)
Perform best in? Milder winter conditions with rain and fast-melting snow; temperatures above and below 7C
What else should you know? All-weather tires are the newest type of tire designed to counter winter conditions. What makes them different from standard winter tires is they maintain good handling in both cold and warm temperatures, but can be kept on the vehicle year-round. However, they are made of a compound that is not as soft as standard winter tires, so they do not perform quite as well in cold temperatures. Still, the compound is softer than all-season tires.
4. All-Season Tires
How to identify? M+S (Mud and Snow) on the sidewall
Perform best in? Milder, dry or slightly wet conditions
What else should you know? All-season tires will not perform as well as standard winter tires in severe conditions; however, all-season tires have a shape and tread design that gives better traction than summer tires in snow and ice. The tire industry indicates M+S tires are made of a hard compound that offers reduced traction when temperatures dip below 7C, compared to winter tires with the 3-peaked mountain and snowflake symbol.
All of these tires are legal on highways with winter tire requirements between October 1 and March 31 or April 30, as long as they have a minimum 3.5 mm tread depth. Tip: pick up a tire depth gauge – they are inexpensive and available at most stores that sell auto supplies.
For maximum stability in cold weather and on ice, snow and slush, we recommend using standard winter tires with the mountain/snowflake emblem. On the other hand, if you only drive in a milder area (ie. Lower Mainland) that gets rain rather than snow, you may choose all-weather or all-season tires.
BC’s diverse range of weather can make tire shopping confusing – we know. That’s why we created a website to help guide your decision. No matter what type of tire you use, your driving performance is one of your best defences against cold, snow and ice. Give lots of space in poor conditions. And remember, speed limits are for ideal driving conditions – think dry asphalt, warm weather, windows down, wind in hair – so, please slow down when necessary.
