MaintainlyHow often should you swap to winter tires?
Swap to winter tires once a year. The commonly recommended range is annually (late fall). Winter tires sharply shorten stopping distance on snow and ice once temperatures drop. This is a safety-critical task, so do not let it slip. It is seasonal work, best done in autumn / fall.
Winter tyres are not simply tyres with more tread. Transport Canada says all-season and summer tyres begin to lose elasticity below 7 degrees Celsius, which means less traction, while a winter compound is made to stay flexible in the cold. The tread also carries many small sipes that bite into snow.
Why does swapping to winter tires matter?
Winter tires sharply shorten stopping distance on snow and ice once temperatures drop.
What happens if you skip swapping to winter tires?
An all-season or summer tyre has less traction once it is cold, before you consider snow or ice. In jurisdictions where winter tyres are legally required in season, running without them also means a fine: $200 to $300 in Quebec.
How do you do it?
- Go by temperature, not by snow. The switch point is around 7 degrees Celsius. Waiting for the first snowfall means the whole city books in on the same day.
- Check tread depth before fitting. Transport Canada advises against using tyres with less than 4 millimetres of tread on snow-covered roads, well above the ordinary legal minimum.
- Check the age of the set. The sidewall carries a date code giving the week and year of manufacture. Rubber hardens with age, so have an older set looked over by a tyre shop even if the tread is good.
- Fit all four, never two. Transport Canada says to install winter tyres in sets of four. Mixing winter on one axle and summer on the other creates a grip imbalance and unpredictable handling.
- Set pressures for the cold. Pressure goes down in the cold. Set to the placard figure with the tyres cold, and check again a week later.
- Torque properly and recheck after a short drive. Same rule as any wheel removal: torque wrench, manufacturer’s figure, and a recheck at the distance the handbook gives.
- Store the off-season set properly. Clean, bagged and out of sunlight, somewhere cool and dry.
What does it take?
How do you know swapping to winter tires is overdue?
- Daily temperatures settling below about 7 degrees Celsius
- Tread below 4 millimetres on the winter set
- Cracking or hardening visible in the tread blocks
What do people get wrong?
- Fitting only two winter tyres, which creates a grip mismatch between the axles
- Leaving winter tyres on through summer, which wears the soft compound quickly
- Confusing the mud and snow marking with the peaked mountain and snowflake symbol: the snowflake is the one Transport Canada tells buyers to look for, and the only marking Quebec accepts
- Storing them in direct sunlight
What changes how often you need to do it?
- A second set of rims makes the changeover fast and cheap and avoids remounting the tyres twice a year
- All-weather tyres, which carry the snowflake symbol and can stay on year round, are a reasonable compromise in milder regions
- Legal requirements in some jurisdictions set the dates for you
When should you stop and call someone?
If you do not have a second set of rims, a tyre shop is the sensible route, since remounting tyres on rims twice a year is not a driveway job.
Does this differ in the US, UK, Australia or Canada?
United States
Rules are set by state and tend to apply to particular roads and conditions. Colorado, for example, can put its traction law into effect on any state highway: all-wheel and four-wheel-drive vehicles then need winter, mud and snow or all-weather rated tyres with at least 3/16 inch of tread, or chains or an approved alternative, and non-compliance carries a $100 fine plus surcharge. Check your state transportation department before a mountain trip.
United Kingdom
Winter tyres are a choice here rather than a routine, and the Highway Code’s tread rule of 1.6 millimetres is the same all year. For most drivers an all-season tyre carrying the snowflake symbol is the more practical answer than a second set.
Australia
Winter tyres are rarely relevant in Australia. The equivalent is snow chains: in Kosciuszko National Park in New South Wales it is compulsory for all two-wheel-drive vehicles to carry chains between the June and October long weekends, and carrying them is recommended for four-wheel and all-wheel-drive vehicles too. Victoria’s alpine resorts set their own chain rules for the declared snow season, so check with the resort before you travel. Outside the alpine areas this task does not apply.
Canada
Quebec requires winter tyres from 1 December to 15 March on motor vehicles registered in the province, including rentals; the tyres must carry the winter pictogram or be studded, and the fine is $200 to $300. British Columbia requires winter tyres or chains on most highways outside the mild coastal areas from 1 October to 30 April, ending 31 March on some routes: a legal winter tyre there carries the M and S letters or the mountain snowflake symbol and has at least 3.5 millimetres of tread, with at least two matching tyres on the primary drive axle. Ontario does not set dates, and its government notes you could get an insurance discount for fitting them.
Frequently asked questions
Why does swapping to winter tires matter?
Winter tires sharply shorten stopping distance on snow and ice once temperatures drop.
What happens if you skip swapping to winter tires?
An all-season or summer tyre has less traction once it is cold, before you consider snow or ice. In jurisdictions where winter tyres are legally required in season, running without them also means a fine: $200 to $300 in Quebec.
Does swapping to winter tires differ by country?
Canada: winter tires grip far better on snow and ice; Quebec legally requires them in the winter months. AU: winter tyres are not used; two-wheel-drive vehicles must carry snow chains in Kosciuszko National Park (NSW) in the snow season, and Victorian alpine resorts set their own rules.
When in the year is swapping to winter tires best done?
This is seasonal work. Plan it for autumn / fall, before the weather it protects against arrives.
