When to put winter tires on in Edmonton: the 7 °C rule
· Just Auto · Tires & Winter
Book your changeover for late September or the first week of October. All-season rubber stiffens below 7 °C, and Edmonton tire shops book out for weeks the day the first snow falls.
Alberta does not require winter tires. The only places in the province that do are the mountain parks, and only on certain highways from November to March. So the question in Edmonton is not whether you are allowed to skip them. It is whether you want to stop in time.
Most drivers here decide in the wrong week. They wait for snow, and by then the phone lines are full.
Why is 7 °C the number?
All-season tires are made from a rubber compound that stays flexible in mild weather. Below about 7 °C it stiffens, and a stiff tire grips less, whatever the tread looks like. Winter tires use a softer compound with more biting edges, so they keep gripping on cold pavement, on packed snow and on the ice that forms at intersections after a thaw.
The 7 °C rule is about pavement temperature, not the forecast high. In Edmonton, overnight lows dip below zero through most of October, so the roads are cold in the morning well before the first snow.
When should Edmonton drivers book?
The realistic window is the last week of September through the middle of November. Two things happen every year inside that window.
- Shops fill up on the first snowfall. Edmonton's first measurable snow lands in October in about half of years and September in some. The day it falls, every tire shop in the city books out for weeks.
- The mornings turn first. By mid October the average overnight low is around zero even when afternoons reach ten degrees.
Booking in late September or the first week of October means your changeover is done before the rush, and you are not driving on stiff rubber through the cold mornings.
Do you need a changeover or a package?
If you already own winter tires on their own rims, a changeover swaps the wheels. If you have winter tires on loose rubber, they need to be mounted and balanced each season. If you have no winter tires yet, a package puts them on a second set of rims so future seasons are a simple swap.

What should you bring?
- Your wheel lock key, if your wheels have locking nuts.
- Your winter set, if you store it at home.
- The tire size from the sidewall or the door-jamb sticker, if you are pricing new tires.
Questions
Are winter tires mandatory in Alberta?
No. Alberta has no general winter tire law. Certain highways in the mountain parks require winter or all-season tires with the mud and snow marking from November to March, but there is no requirement for driving in Edmonton.
Are all-season tires good enough for an Edmonton winter?
All-season tires are built for mild conditions. Their compound hardens below about 7 °C, which costs you grip and braking distance on cold pavement long before there is any snow on the road. They are legal here year-round; they are not the same thing as a winter tire in January.
Do I still need winter tires if my vehicle is four-wheel drive?
Yes, if stopping matters to you. Four-wheel and all-wheel drive help a vehicle pull away on a slippery surface. They do nothing for braking or cornering, which is what the tire compound decides. Most of the vehicles on our lot are 4WD or AWD, and we still recommend winter rubber on them.
Which tire brands can you quote?
We quote and install tires from brands including Michelin, Bridgestone, Goodyear, Continental, Pirelli, Toyo, BFGoodrich and Hankook through the tire finder on our site. Prices are quoted per set for your vehicle's size.
Can tires be financed?
Yes. Tire purchases can be financed, subject to credit approval. Ask when you request your quote and we will include the option.
