As a tire and lube technician (unnecessarily self aggrandizing title) living in Canada, I definitely wanna have a second set of rims for my winter tires, and I'd like to snatch up some good tires when they go on sale, as I'm sure a lot of prospective M3 owners would as well. So which ones? I don't know who knows what, and is allowed to say, but what are we looking at? 18" and 19", Go!!
