Hm good points. It does mention the chains in the supplement. But i can't use not will I ever use chains so 195/50r16 might be a better option.195/50R16 is closer in OD to the stock setup, but my guess is it won't allow enough clearance for chains. I'm sure 15" would work but wonder about any brake cooling issues like the Focus guys are having running 16" steelies.
I used to have a Members Only jacket too but that doesn't mean I wear one today. Studded snows are old-tech unless you have serious arctic conditions all the time. If you live in an area where there may or may not be snow today's studless snow tires are superior and don't tear up the roads.Does anyone drive with studded snow tires instead of chains? That's all I ever drove with growing up. Studded in front, and regular in the back for some good time sideways fwd drifts
