How Long Do Winter Tires Last?
How long do winter tires last? Usually four to six seasons, or roughly 40,000 to 60,000 km of winter driving. The calendar is not the real test, though. Replace them once the tread wears down to 4/32 of an inch, where they stop gripping snow well, and never run any tire more than 10 years old, even if it looks fine.
A good set of winter tires is an investment, so it is fair to ask how long winter tires should last and how many winters you will get out of them. Drivers phrase it a dozen ways, from how long will winter tires last to how long should winter tires last, but the honest answer is the same: time, distance, tread and storage all matter more than any single number. Here is how to tell where your set stands and when it is genuinely done.
How long do winter tires last?
Most winter tires last four to six seasons, or about 40,000 to 60,000 km of winter driving, according to Michelin Canada. At a typical 10,000 km per winter that works out to roughly six years. Yours may land at either end of that range depending on how far you drive, how aggressively, and how well you store them in the offseason. Treat four to six seasons as the planning range, then let tread and age make the final call. So how long do winter tires last in Canada, specifically? That same four-to-six-season window is the Canadian figure, because our cold, salt and freeze-thaw cycles are exactly what the range already accounts for.
How many seasons is that for a GTA driver?
For a typical GTA commuter who runs winter tires from late October to April, that is usually five to six winters. Drive mostly highway kilometres and you may stretch it; pile on stop-and-go city distance, curb the odd pothole, and you may be closer to four. The point is that seasons are a guide, not a guarantee. Two GTA drivers who bought the same tires on the same day can be a season or two apart by the time they wear out.
How do you check if your winter tires are worn out?
Check the tread, in the most worn groove, not by eye. The quick Canadian method is the toonie test: stand a toonie in a main groove, and if the tread reaches the bear's paws you still have plenty, while reaching only the silver edge means they are nearly done. For a precise call, use a cheap tread gauge and measure to the number that matters for winter, which is 4/32 of an inch. Check a few grooves across the tire, because tires often wear unevenly.
What tread depth means it is time to replace winter tires?
Replace winter tires once the tread reaches 4/32 of an inch, which is 3.2 mm. Transport Canada and most provinces use that figure because winter tires lose meaningful snow and ice grip below it, even though the legal minimum for any tire is only 2/32 of an inch, or 1.6 mm. In other words, a winter tire can be street legal and still be too worn to do its winter job. Aim to have at least 4/32 of an inch in the middle of winter, not just at the start.
Do winter tires expire even if they look fine?
Yes. Rubber hardens and cracks with age, so all tires carry an effective 10 year limit from their manufacture date, and Michelin Canada advises against using any tire older than that even if it was never driven. You can read the age from the DOT code on the sidewall, where the last four digits are the week and year it was made. If your winter set is approaching ten years, replace it regardless of how the tread looks.
Check your winter tires in two minutes
- Park on level ground and let the tires cool.
- Do the toonie test, or use a tread gauge, in the main grooves.
- Measure the most worn groove, since tires wear unevenly.
- Replace once you reach 4/32 of an inch (3.2 mm) for winter use.
- Read the DOT date on the sidewall and retire any tire at 10 years.
Does storing them properly make them last longer?
It does, and it is the easiest win. Off the car in the offseason, winter tires last longer when they are cleaned, kept out of direct sunlight, and stored somewhere cool and dry, ideally stacked flat or upright rather than left to bake in a hot garage. Correct pressure and a seasonal swap on schedule help too. We cover the details in how to store winter tires and what tread depth is safe for winter tires.
How long do all-season and all-weather tires last compared with snow tires?
Longer on paper, but the comparison is not apples to apples. How long do all-season tires last? Often 60,000 to 100,000 km, because their harder compound wears more slowly. How long do all-weather tires last? Usually a little less than an all-season, since the softer winter-rated compound trades some tread life for cold grip. And how long do snow tires last? The four to six seasons above, because that same soft compound is exactly what makes them grip in the cold.
So a winter tire wears faster by design, and that is the point: you are spending tread life to buy traction when it matters. If you are weighing the trade, our guides on all-season vs winter tires and all-weather tires for winter lay it out.
When it is time for a new set, how do GTA drivers pay less?
A fresh set of four winter tires is not cheap, and shopping alone gives you no leverage. That is the gap Whollar closes. Rather than buying one car at a time, drivers in the same area bring their demand together into one cohort, and installers compete to serve everyone, which helps on the price of the set and the fitting. You see the offers and decide whether to buy, with no obligation. Starting a fresh set, our size tool shows the right winter tire size to begin with.

Frequently asked questions
How long do winter tires last?
Usually four to six seasons, or about 40,000 to 60,000 km of winter driving. How far and how hard you drive, plus offseason storage, decide where in that range you land.
At what tread depth should you replace winter tires?
At 4/32 of an inch (3.2 mm). Below that, winter tires lose meaningful snow and ice grip, even though the legal minimum for any tire is 2/32 of an inch (1.6 mm).
Do winter tires expire?
Yes. Rubber ages, so no tire should be used more than 10 years from its manufacture date, even if the tread still looks good. Check the DOT code on the sidewall for the date.
How do you check winter tire tread?
Use the toonie test or a tread gauge in the main grooves, and measure the most worn groove. Replace once you reach 4/32 of an inch (3.2 mm) for winter use.
Can you make winter tires last longer?
Yes. Keep the correct pressure, swap them on schedule, and store them clean, cool, dry and out of sunlight in the offseason. Good habits can add a season.
