Given the depth being brought out in this discussion, perhaps I should pose this question:
OEM on the Dasher was 13", there is a rusty dry-rotted example in the spare tire well. Current fitment is 14x~6.5" Ronal R-8s with 195-60/14s. What I choose as a goal is to have a summer and winter set of wheels, to spread out wear and replacement (yeah, right). The summer wheels at 14" locks in the 195/60 size circumference. I can't afford to lose the current overall ratio.
For winter what I would like is 15" steelies. What I understand is that mud, snow and ice all require difference treads and compounds. Sidewalls that virtue signal battlecar status is
probably more important than actual off-road performance.
Hydroplaning resistance is right up there.
