A guide for fleet operators, owner-operators and drivers
Why it’s important to use the right tires in winter driving conditions
BC’s unique terrain, changing elevations and unpredictable weather make this one of the most demanding winter driving environments in North America.
- for more than half the year – from early October to late April – weather conditions can change from summer-like to winter with little or no warning.
On most major highways outside Greater Vancouver and southern Vancouver Island:
- commercial vehicles weighing between 5,000 kg and 11,794 kg LGVW must carry chains (or other acceptable traction devices), unless equipped with winter-rated tires (identified by the 3-peaked mountain and snowflake symbol or the M+S symbol).
- commercial vehicles weighing 11,794 kg LGVW or more must carry steel chains and are recommended to use tires suited for winter driving.
Using the right tires in winter increases safety and reliability
To improve driver safety and to protect your equipment and other road users, commercial vehicle owners should:
- equip vehicles with tires best suited to the routes they travel
- train drivers to safely navigate winter road conditions, inspect tires and properly install chains. Visit https://shiftintowinter.ca/worker-tools/ commercial-trucking-resources/chaining-up/
- keep vehicles in top winter operating condition
Drivers of trucks properly equipped for winter conditions are more confident and experience less fatigue and downtime.
Road closures caused by vehicles getting stuck, spinning out or running off the road costs everyone time and money.
Drivers and dispatchers need to pay attention toweather warnings and road reports to decide if it’s safe to proceed or if a trip should be re-routed or postponed. For information about current road conditions, weather warnings or delays consult DriveBC.ca.
Matching tires to road conditions – industry best practices
The routes you travel in winter will dictate your decision – for example, if business takes you:
- across northern BC or across Canada – prepare for extreme cold and snow and ice all winter
- through mountain passes – equip to tackle grades and prepare for sudden changes in weather – even in the fall and spring
- north – south (e.g. from BC to Mexico) – expect everything from extreme winter to heavy rainfall to summer heat
- off-road – equip for mud, hard-packed snow and ice
- in Greater Vancouver or southern Vancouver Island – expect cool, wet weather and occasional snow
Consult your tire supplier and follow industry best practices concerning tire choices:
- choose tires best suited to the routes you regularly travel
- consider factors such as rubber compound, tread pattern and tread depth
- install new tires or retreads in the fall so they are in optimal condition heading into winter
- choose tires designed for winter conditions even if travelling where chains are not required
- although lighter commercial vehicles (weighing less than 11,794 LGVW) are required to use winter-rated tires OR carry chains (where specified), best practice is to use winter tires AND carry steel chains or other traction devices such as cable chains or wheel socks.

Tire wear and fuel economy
Choosing the right tires for winter use requires research and talking to tire suppliers:
- tires with an aggressive tread pattern will work well in certain winter conditions but may be less fuel efficient.
- tires with higher natural rubber content are softer and provide better traction in cold temperatures, but will wear faster in warm, dry conditions.
- tires with higher synthetic content wear more slowly but may tear and chunk in extreme winter conditions.
New tires vs. retreads:
- equipping commercial vehicles with retreads may be a more cost-effective and eco-friendly option than always buying new tires.
- retreads are available in a variety of rubber compounds and tread patterns.
- investing in good quality casings will extend tire life and reduce long-term costs.
- retreads can be used on drive axles and trailers, but not on steer axles.
Consult your tire supplier to determine which tires are best for you.
