If anything, with AWD, you're more likely to accelerate faster and say "BAHAHAH!!! Suck on snow you Bitchez!!" resulting in the need to brake a little faster.
Get them on and save your ride/another ride/a life or 2 even.
Montreal got over over 200cm of snow compared to T.O 130cm.
No way did we get that much...
I'm hoping for a whole whack ton of snow this season!
