Just thinking of what I will be doing for accessories on the Model 3, I know I will be buying a second set of wheels/tires to be used for winter driving as I live in Canada. This is a necessary evil of living so close to the Rocky Mountains and being able to enjoy a vehicle year round. I see the Model S is using BMW wheel offsets and bolt patterns, is this likely to be the same for the Model 3? Also, what would the default wheel size be 18/19/20 inches? Thoughts?
