An all-season tire stiffens as the temperature drops and loses meaningful grip below roughly 45°F, regardless of how much tread is left — that's a rubber-compound issue, not a wear issue. Winter rubber stays pliable well past that point. Current hours: Mon–Fri 7:30 AM – 7:00 PM, Sat 7:00 AM – 7:00 PM, closed Sun.
An all-season tire doesn't fail in cold weather so much as it stops being much of a tire at all. The rubber compound stiffens as the temperature drops, and below a certain point it grips a cold road about as well as a hard plastic wheel would. Winter rubber is formulated to stay pliable well past that point — that's the real difference between the two, not the tread pattern most people point to first.

Why do all-season tires lose grip in the cold even with plenty of tread left?
Tread depth measures wear, not stiffness, and a cold-weather grip problem is a stiffness problem. Below a certain temperature the compound in an all-season tire hardens enough that it can't flex into the small contact patch it needs on a cold or icy surface, no matter how much tread remains. A tire with half its tread life left can lose grip the same way a badly worn one does, just for a different reason entirely.
What happens if only two tires go on instead of a full set?
It happens, usually on a budget, but it creates a mismatch between the axles that shows up as unpredictable handling in exactly the conditions winter tires are meant to help with — one end of the car grips and the other doesn't. Two winter tires up front on a front-wheel-drive car is the most common version of this shortcut, and it's also the one most likely to bite on a turn, because the rear end loses grip first and without warning.
At what temperature do winter tires actually start to matter?
Most all-season compounds start losing meaningful grip somewhere below 45°F, well before ice or snow shows up. That's the reason winter tires are worth having even in a light snow year — the cold alone is enough to matter.
Can I just wait until the first snow to book a swap?
Current hours: Mon–Fri 7:30 AM – 7:00 PM, Sat 7:00 AM – 7:00 PM, closed Sun. Booking on a weekday, or the Saturday before the forecast turns, avoids the scramble.
Are winter tires unsafe once the weather warms back up?
The same soft compound that grips cold pavement wears faster and feels vaguer on warm, dry roads, so they should come off again once temperatures are reliably back above that range. It's more a performance and tire-life issue than a safety cliff, but it's still worth swapping back.
