Hey guys so I have a 2014 Mazda 3 with the stock wheels still on. I live in Canada where the winters get really bad so I wanted to prepare and have a pair of winter tires ready for when it gets bad. I currently have 16" rims but would it be better if I go for something bigger like 18"? Originally I was going to get the Continental ExtremeContact DWS tires but I think a dedicated set of winter tires will be a lot better. I'm also planning on keeping my stock rims for the winter tires and finding an all season set for the summer if that changes anything. So what do you think the best winter tire/size would be for a Canadian winter? Thanks!
